Was-alhum AAani alqaryati allatee kanat hadirata albahri ith yaAAdoona fee assabti ith (surah Araf: 163)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(7:163) And ask the people of Moses concerning the town situated along the sea *122 how its people profaned the Sabbath when fish came to them breaking the water's surface on Sabbath days, *123 and would not come to them on other than Sabbath-days. Thus did We try them because of their disobedience. *124

Was`alhum `anil qaryatil latee kaanat haadiratal bahri iz ya`doona fis Sabt iz taateehim heetaanuhum yawma Sabtihim shurra`anw wa yawma laa yasbitoona laa taateehim; kazaalika nabloohum bimaa kaanoo yafsuqoon

*122). Most scholars identify this place with Eilat, Eilath or Eloth. (Cf. Encyclopaedia Britannica, XV edition, 'Macropaedia', vol. 3, art. 'Elat' -Ed.) The seaport called Elat which has been built by the present state of Israel (which is close to the Jordanian seaport, Aqaba), stands on the same site. It lies at the end of that long inlet of the Red Sea situated between the eastern part of the Sinai peninsula and the western part of Arabia. It was a major trading centre in the time of Israelite ascendancy. The Prophet Solomon took this city as the chief port for his fleet in the Red Sea.
The event referred to in the above verse is not reported in Jewish Scriptures. Nor do historical accounts shed any light on it. Nonetheless, it appears from the way it has been mentioned in the above verse and in al-Baqarah that the Jews of the early days of Islam were quite familiar with the event. (See Towards Understanding the Qur'an, vol. 1, al-Baqarah 2: 65 and n. 83, pp. 81-2 - Ed.) This view is further corroborated by the fact that even the Madinan Jews who spared no opportunity to criticize the Prophet (peace be on him) did not raise any objection against this (Qur'anic account.
*123). 'Sabbath', which means Saturday, was declared for the Israelites as the holi day of the week. God declared the Sabbath as a sign of the perpetual covenant between God and Israel. (Exodus 31: 12-16.) The Israelites were required to strictly keep the Sabbath which meant that they may not engage in any worldly activity; they may not cook, nor make their slaves or cattle serve them. Those who violated these rules were to be put to death. The Israelites, however, publicly violated these rules. In the days of the Prophet Jeremiah (between 628 and 586 B.C.), the Israelites carried their merchandise through the gates of Jerusalem on the Sabbath day itself. Jeremiah, therefore, warned them that if they persisted in their flagrant violation of the Law, Jerusalem would be set on fire. (Jererniah 17: 21-7.) The same complaint is voiced in the Book of the Prophet Ezekiel (595-536 B.C.) who referred to their violation of the Sabbath rules as their major sin. (Ezekiel 20: 12-24.) In view of these Scriptural references it seems plausible that the event mentioned in the above Qur'anic verse is related to the same period.
*124). Men are tested by God in a variety of ways. When a person or group of people begin to turn away from God and incline themselves towards disobedience, God provides abundant opportunities for them to disobey. This is done in order that the full potential for disobedience, which had remained hidden because of lack of such an opportunity, might come to the surface.
