Preferred Frames of Reference

Submitted without comment: how to pray facing Mecca from low-Earth orbit. An excerpt from “The Determination of Prayer Times and Direction of the Qiblah in Space,” by Dr. Zainol Abidin Abdul Rashid, translated from Malay by Jessica Ramakrishnan, published in the November issue of Harper’s, and also here. Presented at a conference on Islam and Life in Space.

As trips to space become commonplace, human civilization will no longer be tied to the surface of the Earth. But Muslims, wherever they are- whether on Earth or in space – are bound by duty to perform the obligations of worship.

A Muslim who wants to travel must study the techniques of determining prayer times and the direction of the Qibla ahead of travel in order to achieve complete worship. I will elaborate the method of determining prayer times and the Qiblah direction in space, primarily on the International Space Station (ISS). The ISS is more than 200 miles from the earth’s surface and orbits the earth every ninety-two minutes, or roughly sixteen times a day. Do we have to worship eighty times a day (sixteen orbits a day multiplied by five prayer times?) This seems unlikely, since it is compulsory for a Muslim to pray five times a day according to an Earth day, as determined by Allah during the creation of Heaven and Earth – no matter where in space the Muslim is located.

As for the Qiblah, for Muslims there is only one the Kaaba, located in Mecca. A Qiblah that changes in references to a specific system is not in order! It must be remembered that Allah’s creation is ordered.

A user-friendly, portable Muslims in Space calculator , could determine the direction of the Qiblah and prayer times on the ISS. Its essential feature would be the use of the Projected Earth and Qiblah Pole concepts. These are based on the interpretation of the holy house of angels in the sky above Mecca. The place is always rich with angels worshipping. As many as 70,000 angels circumambulate it every day. Thus, one virtual Qiblah pole can be taken as a universal reference to determine the direction of the Qiblah. When Earth is projected to the height of the ISS, every point on its surface is projected also, including the Qiblah point, which can be projected upwards and downwards along the Qiblah Pole. This allows the direction of the Qiblah to be determined in space and in the bowels of the Earth.

  1. An orthodox Jew was quite upset to find herself on a commercial aircraft as the sabboth started (sunset). She said she’s not allowed to travel on the sabboth, since that’s hard work. How sitting on an airplane and being served your veggie (kosher) meal is hard work is beyond me. The plane lifted off of the ground just after sunset, and once airborne, the Sun was clearly visible. And as we were quite a ways North, and as we were flying to the West, it turns out that the Sun had not set by the time we landed. There was still a half hour before sunset.

    Now, by the time we landed, she had come up with a loophole in the law, and felt herself not in violation. I won’t go into it. From my perspective, she saw an additional sunset, and her week was now a day out of sync with everyone else. That one sabboth was only about 15 minutes long. That is, unless the sacred texts require that the Sun rise in the East, rather than in the West. I’ve read them, but don’t recall the details.

    Even when the Bible was written, people could have walked to Norway and experienced a three month long day or night. I don’t expect that the Bible authors could have foreseen air travel. If you flew the Wright Flyer, the circumpolar flights would have been hard to imagine.

    Perhaps that’s why i’m not a Biblical literalist.

  2. Yes, PK, I would say it is made up. Jihad in its popular meaning and its original one are completely different. Basically it means to strive against evil. Mainly against your own shortcomings like lust, anger etc. etc. Islam is not what we know it to be.

    “Unfortunately, most of the Arab world is now in the dark.” I disagree. I feel it is almost all, if not all.

    “I wouldn’t attribute this enlightened period to Islam, though” Unless Islam were friendly towards gathering knowledge(‘ilm) you would not see what you see. We know that scientific temper and the Church don’t go well (I like to differntiate between the Church and Christianity). It did not come from void either. A deep look at the current scietific temper, Islam and history will tell you that much(not all) of it actually comes from Islam. We just don’t know where it comes from. The Mullahs of the present are fools at best. Hardly a good source to learn or form an impression of Islam.
    There would be no political stability in Arab had there been no Islam. Arab was it turmoil before Islam came. It even gave eastern Europe and Spain a breath of peace. Perhaps you will agree that science advances only under a sympathetic peaceful regime.

    I bet you would be surprized if I tell you that the paradigm shift from deductive(example Euclidean geometry) to inductive (experiment and observation based) science actually occured in Arab. And it was influenced by the provocation of the Qur’an (there are verses like “have you ever reflected upon how rain falls” and similar ones.) that urges you to draw conclusion from observation.

    Did you know that the current definition of religious tolerance come from Islam? I bet you didn’t. You could have a quick review of the history of Spain, Bulgaria, Palestine (it will be counterintuitive if you try to project backwards from present, though ), India and many other places. An article by an Isaeli peace activist will tell you.

    Did you know that modern war ethics (like not attacking civilians, civilian property and the ethics of handling the prisoners) can be traced back to Muhammad?

  3. But yup! After all this, I did not like so much fuss about ‘Quiblah pole’. Calling a big conference to discuss such trivial thing when you can’t make your own rockets is…

    Well I don’t like it.

  4. Manas,

    I’m not sure how you can characterize Spain under Islam as a “breath of peace”. Under Cordoba, there were frequent raids into Christian areas (see e.g. the sack of Barcelona 985) and raids from the Christians into Spain. After the collapse of the caliphate, there was a lot of warfare between the taifas, not to mention struggles with the Christian kingdoms in the North of Spain, crusade and jihad, and two full blown invasions from the Almohads and the Almoravids.

    It’s also curious to characterize Eastern Europe as peaceful under Islam – I assume you mean the Turks? This would be the same Turks who specialized in kidnapping the sons of Christian subjects, forcing them to convert to Islam, and sending them out every few years to campaign against Christian states in Eastern Europe? Was it peace that the Turks brought to Vienna in 1529 and 1683? Or was it peace that the Turks brought to Hungary in 1526, 1541, or in 1620?

    India is a rather strange example to bring up of religious tolerance. It’t true that the Mughals did have periods of religious tolerance under Akbar, but then they also had periods of extreme intolerance under Aurangzeb, who destroyed countless Hindu temples, and converted many to Islam by force. That led directly to what you might expect: constant rebellion by Hindus and the formation of the Sikh religion in opposition to the Mughals. It’s also true that Islam came to North India mainly through conquest and horrific bloodshed – how many times was Delhi sacked?

    I’m also very dubious about your claim that our ideas about religious tolerance comes from Islam. I don’t recall us requiring non-Muslims to pay a head tax (required under sharia), or to wear clothes of a certain color (sharia again), or forbidding construction of non-Muslim place of worship (sharia law – still law in Egypt by the way!). I also don’t remember us having no legal protections for religions not of the Book.

    I’m curious – would these modern war ethics of Mohammed include the execution of all the male members of a tribe after they surrendered to you, and then the sale of their women and children into slavery (the Banu Qurayza)?

    I guess you’re right – there was never religious tolerance before Islam, and no one ever elucidated modern war ethics before Mohammed. After all, at the signing of the Geneva conventions, I well remember the many speeches given on the example of Mohammed.

  5. cf Christmas as brought to India and the Southern Hemisphere by the British.
    (Or for that matter in Los Angeles and Phoenix.)
    White plastic snow, santa claus in red flannels + reindeer, christmas trees, all with blazing hot sun outside.

    And this is, to be fair, not even completely the work of the Christians, and thus to be blamed on religous stupidity. Human culture is a beast of epic idiocy, whether yoked to religion or not.

  6. Dear Hektor Bim,

    I feel
    1. You suffer from generalization.
    2. Islam is not always reflected in what a Muslim does

    Generalization
    Just as the Church often failed to practice love and equality as preached by Jesus, Muslims have failed in their duty too.
    Given that, the general environment under Muslim rule was far more conductive than under a Christian rule. In Muslim Spain (which interestingly was invaded by African Moors, blacks, who came as a civilizing force) Christians and Jews held positions in Office as well as scholars among them were patronized. Isolated incidents do not prove the rule.
    As opposed to that, when the Moors were defeated by Ferdinand and Isabella, the minority Jews and Muslims had either to convert to Christianity or they had to flee. A population of 15% Muslim reduced to almost nothing. Whereas when the Muslims had ruled, Christians remained majority and no systematic effort was in place to convert them.

    Do not generalize from isolated incidents. If Islam preached forced conversion, whole of Bulgaria and a number of other countries would be Muslim now.

    Have a look at history of Europe and you will know what I mean when I say Islam came as breath of peace. Killings and fights were normal in Europe. No country that was ruled by Christian rulers had any of their original religions left. There was a systematic effort by the rulers to create a monolithic society.

    I well remember the many speeches given on the example of Mohammed.

    This is the problem. You do not cite the source and then deny the author his credit. Same with science. There is a deliberate effort in all science texbooks to use as far as possible Greek and European names and avoid Arab or Indian names, so that nobody grows suspicious that Arabs contributed significantly to Science and Technology. Even as an eager ear as myself never knew that until recently.

    In the example that you cite you do not tell the whole story. As far as I am aware, the people you say surrendered were actually defeated and captured. And you do not talk about what they did before being captured. Please learn to tell the whole story.

    Islam is not always reflected in what a Muslim does

    Just as what a scientist says may alway not be right.

    Islam does not teach you to oppress others.

    There are a lot of things to take into consideration. The kings found religion as a good vehicle of generating sympathy. So they slaughtered people in the name of religion. It holds for everyone, the Muslims the Christians, the Jews. The question is how do they fare in relative terms.

    You mention Jihad. Please get your history right. It was the Church that called for Crusade. The Muslims were surprized and overwhelmed in the first Crusade. In the second they united and defeated the Christians. And did not lose after that in the third and fourth Crusade. Crusade is a shame in the Church’s history (but again, then the Church was wrong and not Christianity).

  7. I’m also very dubious about your claim that our ideas about religious tolerance comes from Islam. I don’t recall us requiring non-Muslims to pay a head tax (required under sharia), or to wear clothes of a certain color (sharia again), or forbidding construction of non-Muslim place of worship (sharia law – still law in Egypt by the way!).

    You just have to contrast it with how the Christians dealt with Jews and occasionaly Muslims. Or maybe how the Hindus dealt with the Buddhists. Buddhists, on the other hand (again not without exception, but you should not generalize) has had a good tolerant history. That is why in Buddhist China Jorathrustians (spelling must be wrong) still survive.

    I never said religious tolerance did not exist before advent of Islam. I am saying the modern version comes from Islam. Tolerance got buried under old rug. Islam pulled it out.

    I also don’t remember us having no legal protections for religions not of the Book.

    Have a look at the Qur’an, you will. I’ll give three verses

    “your (Muhammad’s) duty is only to proclaim”.

    “if they (still) do not believe, say ‘peace’ and turn away”

    “had it been your Lord’s will, everyone of them would have believed, will you then force them to believe?”

    Sidenote: there are many debates about Sharia laws. They are not unchallenged. (I mean within the Musilms too)

  8. Manas,

    I just wanted to point out that there wasn’t as much oppression of Buddhists under Hindu rulers as you like to think. I haven’t seen anything about forced conversions, for example. I am sure it was not without exception, but you should not generalize 🙂

  9. Sorry, but a second note on Manas-spins “Buddhists, on the other hand (again not without exception, but you should not generalize) has had a good tolerant history. That is why in Buddhist China Jorathrustians (spelling must be wrong) still survive.” The Hindu history isn’t that intolerant either otherwise Islam (and a host of other religions) in India would not have survived 🙂

  10. Manas, I think it is generally broadly recognized that the survival of the Greek tradition through the Middle Ages is almost exclusively due to the Arabs, and that they contributed much to mathematics. However, I do not see so many Arab contributions in physics (or “natural philosophy”) that have survived. No improvement over Ptolemy that was finally superseded by Copernicus, no refutation of Aristotle to keep us going until Galileo. I may well be wrong, so if I have missed something I would very much like to hear about it.

    I would say that the “deliberate effort in all science textbooks to use as far as possible Greek and European names and avoid Arab or Indian names […]” is a bit of a conspiracy theory. I think it is ignorance at worst. Think about it: for a textbook writer to find an earlier source of a concept is a major bonus. If I were to write a textbook on celestial mechanics and knew about a pre-Copernian heliocentric system, I would most definitely include it!

  11. So Sean, which way should one face when in the North Pole, and which way should one face when sitting on the other side of the moon

    Incidentally on Earth whether one faces east or faces west, isn’t one ultimately facing the same ‘point’ whether it be the short or long way? – or can one only cross the atlantic from east to west, that is from the west coast of europe + africa, to the east coast of america (north & south) or Canada.

    Funny, there was a time when you could only go to the Indies heading east until not so long ago (514 years ago?), and the story goes a certain chap called christopher columbus had to wait till the ‘reconquest’ of Spain by Isabela & Ferdinand, to get his ships to travel west in search of the Indies. But this could all be myth, hearsay or ‘Spanish’ propaganda.

  12. PK

    I do not see so many Arab contributions in physics (or “natural philosophy”) that have survived.

    As far as I am aware, you are right. There was not much work on ‘natural philosophy’ or rather topics related to physics. You can have a look at the book referred at the end of this post.

    Chemistry, on the other hand, was almost exclusive gift of the Arabs. And it was based on experiments. Now remember that all textbooks do tell us that they started the tradition. But while discussing chemicals, their preparation etc. they fail to remember the relevant Arab names. Whereas while discussing ‘recent’ advancements, it hardly forgets tha man/woman behind.

    …is a bit of a conspiracy theory. I think it is ignorance at worst. Think about it: for a textbook writer to find an earlier source of a concept is a major bonus. If I were to write a textbook on celestial mechanics and knew about a pre-Copernian heliocentric system, I would most definitely include it!

    A simple test: you ask any man on the street about Arab’s contribution to science and that of Greek. Their answer will point to the different amount of emphasis placed on the two nation’s contribution. (don’t generalize from your own point of view). The bonus you talk about is actually a threat to white superiority for some. It may be hard to believe for you. Fact of life is the Greek contribution to ‘natural philosophy’ is easily accessible information, while that of Arabs is not that much.

    Greeks used to observe stars. So did the Arabs. And Arabs identified and named a significant number of visible stars. There was a famous observatory somwhere in Iraq. I did not know that until recently. But from my childhood I knew quite well about Tycho Brahe and his student, (they ofcourse deserve to be known, but so do the Arab observers).

    It is not that Arabs are competely denied credit. It is that texbooks often do not refer to specific names.

    Have a look at this book ‘Arab Scientists’ by Francis Bacon. (I could not find it on Amazon) or this.

  13. Chinmaya
    During the Mourya Dynasty there was a significant number of Buddhists in India. When it fell, and Gupta dynasty rose to power, Buddhists suddenly almost disappeared from the demographic map of India.

    Muslims would not have survived had Hindus been rulers of significance for significant time. You see the process going on now. But this is not the place to debate that.

  14. and the story goes a certain chap called christopher columbus had to wait till the ‘reconquest’ of Spain by Isabela & Ferdinand, to get his ships to travel west in search of the Indies. But this could all be myth, hearsay or ‘Spanish’ propaganda.

    It’s all in your mind. You want to know why ‘a certain chap called christopher columbus’ had to go in search of Indies.

    It was because of the fall of Constantinople (remember, if you knew that fall of constantinople and fall of Moorish empire occured around same time.) Perhaps you are aware that there was trade relation between India/China and Spain/Europe through Constantinople/Arab. As Constantinople fell, and the new rulers of Spain were not particularly friendly with them, they had to look for alternative rout, which was the sea rout.

    There is no spanish propaganda, you imagined it! 🙂

  15. “Hmm… I see all of you are very sure about 72 virgins. Can any of you kindly help me locate the verse that promise it?”

    Worse yet — where in the sayings of the Prophet is it declared that those virgins will be HUMAN???? Will all good suicide bombers be presented with a shoebox full of 72 virgin mice???

  16. Manas,
    I think your are being dishonest manner.
    Show me a single source that shows that a single Hindu ruler was as barbaric as Aurangzeb (someone who is still admired in Pakistan). And you say there is some “process” going on in India where the Hindus don’t want Muslims to survive. Pathetic! I think Hektor Bim is exactly right.

  17. Manas Sheikh brought something up but does not want to debate it here.
    In that vein, let me bring up a point and not debate it here – in 1193, Bakhtiar Khilji sacked the center of Buddhist learning, the university of Nalanda. That was a key milestone of the decline of Buddhism in India.

    Regarding the survival of Hinduism in India – most of the “high civilization” – philosophy, sciences, arts was destroyed or greatly diminished by the Islamic invasions, and what survived was the decentralized, the “folk” arts and religion. There is no need to sugarcoat this fact.

  18. I regret bringing it up here. But not what I said.

    This is not the place to discuss Indian history. Lets stick to the topic. I have already said I am open to discussion where it is relevant.

  19. Thanks Manas. The presenter, Adam Hart-Davis, is well-known here for these programs, and I must have missed this episode when it was first aired.

    Interestingly, the Arabs improved the precision of the earth’s tilting angle in order to better tell the time to pray. But in practice I’m sure economics (travel and all that) had something to do with it as well (cf. the multitude of uses for the astrolabe). As Hart-Davis says at the end: The Arabs preserved, expanded, and improved the knowledge of the ancient Greeks. Without them, modern life would look very different indeed.
