This episode belongs to the time of Sayyidna Dawud (David (علیہ السلام Allah had appointed Saturday as the Sabt سبت ، or the sacred day, for the Israelites; it was specially set apart for prayers and worship, and hence fishing was prohibited on this day. But these people lived on the sea-shore, and were very fond of fish. Al-Qurtubi says that the Israelites, at first, invented all sorts of clever pretences for catching fish on Saturday, and gradually started doing so openly. There now grew a division amongst them on this point. On the one hand were these transgressors, and, on the other, some scholars and pious men who tried to dissuade them from such disobedience. When the former paid no heed to them, the latter broke away altogether from the sinners, and began to live in a separate part of the town. One day they felt no sound was coming from the other part of the town. Growing curious, they went there and found that all the transgressors had been changed into apes. Qatadah says that the young ones had become apes, and the old ones swine. The apes could recognize their relatives and friends, and would approach them weeping out of remorse, and seeking their sympathy and help. Then all of them died after three days.
As to the question whether the apes and the swine we see today bear any kinship to these Israelites who had been metamorphosed, the correct position is that people who have been metamorphosed into beasts by Allah as a punishment cease to breed, and leave no progeny behind. According to a hadith reported by Imam Muslim from the blessed Companion ` Abdullah ibn Masud ؓ some people asked the Holy Prophet ﷺ whether the apes and the swine were the descendants of the metamorphosed Jews. The Holy Prophet reminded them that apes and swine existed in the world even before, and said that when Allah sends down this particular kind of punishment on a people, the race comes to an end with this, and there is no further breeding.24
24. Some 'modernizing' Muslims have tried to explain away this metamorphosis by suggesting that these disobedient Jews did not actually and physically turn into beasts, but that the change was only psychological in so far as they acquired the evil characteristics of apes and swine. To say such a thing is to deny an explicit statement of the Holy Qur'an, which no Muslim can do, if he wishes to remain a Muslim. Moreover, in denying the possibility of physical change, the 'modernizers' are also denying the power of Allah, and putting limitations on it. Even as a piece of literary exegesis, the 'modernist' interpretation is flimsy. For, even before the punishment fell on them, these Jews had been displaying the moral and psychological traits of beasts: the greed of swine and the craftiness of apes. Where was, then, the change which the Holy Qur'an declares to be a punishment for the offenders and a warning for others? Our 'modernists' are, in fact, all too ready to swallow without batting an eye-lid the most preposterous and unfounded notions, only if they come from the West. So, they have complete certitude with regard to Darwin's speculation, that the apes evolved into man, although no verifiable data has yet been gathered to support the contention; but when it comes to the statement in the Holy Qur'an that men were changed into apes, they look askance at it, although this kind of change is rationally and logically as possible as the other.
Let us now go back to the verse under discussion. The people who witnessed the event, or heard of it, were of two kinds - the disobedient and the obedient. For the disobedient, it served as a 'deterrent', an example and a warning, which persuaded them to repent of their disobedience. For the obedient, it was a lesson and a reminder that they should be steadfast in their obedience. It serves these two purposes even now.
Injunctions and related considerations
We have been saying that the Jews who were changed into apes had used certain ruses or pretences to justify their sin in their own eyes. This brings us to a rather delicate question of Fiqh فقہ (Islamic jurisprudence). Certain 'modernists' have quite shamelessly been busy maligning the master jurists of Islam by suggesting that these masters have invented very intricate "stratagems" (Hiyal, plural of Hilah) for helping the rich and powerful to infringe the laws of the Shari'ah and get away with it. This is a petty calumny, and should not have been worthy of consideration except for the fact that such 'modernists' have had some success with the gullible and the ignorant by playing upon the Arabic word Hilah. As everyone knows, the lexical meaning of a word is one thing, and its technical signification, when it is used as a term in some science, is another. In its literal sense, the word Hilah no doubt means "a trick, a stratagem", but as a technical term in Fiqh فقہ it signifies a device for and a means of giving legitimacy to an action in a contingency by making certain necessary modifications in it in consonance with the 'Shari` ah. Thus, it is not a way of by-passing the Shari'ah, but of helping people to conform to it even in a situation where necessity or human weakness would compel them to go against it.
The present verse has a particular relevance to the question, and would help to clarify it a great deal. The transgression on the part of the Jews which the verse speaks of, and which drew upon them such dreadful punishment, was not a clear and explicit infringement of divine law, but the use of certain "tricks" which necessarily involved the negation of the divine commandment. For example, on Saturday they would tie one end of a cord to the tail of a fish and the other end to something on the shore, and leave the fish in the water; on Sunday, they would take it out and eat it. Such a ruse not only negates an injunction of the Shari'ah, but is actually a mockery. That is why those who practiced such "stratagems" were considered to be disobedient and rebellious, and subjected to dire punishment.
But this particular instance does in no way go to prove that the Hiyal are impermissible. We have explained the nature and purpose of such "devices" alone. Not only do they form an integral part of Fiqh فقہ ، but some of them have actually been suggested by the Holy Prophet ﷺ himself. For example, bartering a kilo of good dates for two kilos of bad dates is, according to the Shari'ah, a kind of usury. The Holy Prophet ﷺ has suggested a "device" (Hilah) for avoiding the infringement of this regulation in a situation where such a transaction becomes necessary - that is, instead of bartering one commodity for another, one may employ the exchange value of money: first sell two kilos of bad dates for two rupees, and then with the two rupees thus obtained buy a kilo of good dates. The intention in using this "device" is to conform to the Shari'ah, and not to by-pass it. The negation of the Shari'ah is neither intended here, nor does it actually take place. This principle holds good in the case of all the Hiyal which the Fuqaha-' (jurists) have proposed in order to save people from practicing what the Shari` ah has prohibited. It is a travesty of the truth to compare them to or represent them as the "tricks" employed by the Jews to negate and mock the Shari ah.
