Translation of the verse 160 from Surah Al-A‘raf : Number of verses 206 - - page 171 - Part 9.
And We divided them into twelve tribes (as distinct) nations. We directed Musa (Moses) by inspiration, when his people asked him for water, (saying): "Strike the stone with your stick", and there gushed forth out of it twelve springs: each group knew its own place for water. We shaded them with the clouds and sent down upon them Al-Manna and the quails (saying): "Eat of the good things with which We have provided you." They harmed Us not but they used to harm themselves.
And We divided them into twelve descendant tribes [as distinct] nations. And We inspired to Moses when his people implored him for water, "Strike with your staff the stone," and there gushed forth from it twelve springs. Every people knew its watering place. And We shaded them with clouds and sent down upon them manna and quails, [saying], "Eat from the good things with which We have provided you." And they wronged Us not, but they were [only] wronging themselves.
(7:160) And We divided them into twelve tribes, forming them into communities. *118 When his people asked Moses for water We directed him: 'Smite the rock with your rod.' Then twelve springs gushed forth from the rock and every people knew their drinking-places. And We caused thick clouds to provide them shade, and We sent down upon them manna and quails, *119 saying: 'Eat of the clean things that We have provided you.' They wronged not Us, but it was themselves that they wronged.
*118). This refers to the organization of the people of Israel which has been mentioned in the Qur'an in al-Ma'idah 5:12 and also described, at length, in the Bible in Numbers. According to these sources, in compliance with God's command the Prophet Moses first conducted the census of the Israelites in the wilderness of Sinai. He registered their twelve tribes, ten of whom were descendants of the Prophet Jacob, and the remaining two descendants of the Prophet Joseph, as separate and distinct tribes. He appointed a chief for each tribe and assigned to him the duty to maintain moral, religious, social and military discipline within each tribe and to enforce the Law. The Levites, who were descendants of the Prophets Moses and Aaron, however, were organized as a distinct group entrusted with the task of providing religious guidance to all tribes.
*119). This organization was one of the numerous favours which God had bestowed upon the Israelites. Mention is made of three other favours bestowed upon them. First, an extraordinary arrangement for their water supply was made in the otherwise arid Sinai peninsula. Second, the sky was covered with clouds such that they were protected from the scorching heat of the sun. Third, a unique meal, consisting of manna and quails was sent down on them. Had this Divine arrangement, catering as it did for the millions of wandering Israelites' basic necessities of life, not been made, they would certainly have perished.
On visiting that land even today it is difficult to visualize how such an arrangement providing shelter, food and water for millions of people was made. The population of this peninsula standseven today at a paltry, 55,000 people. (it may be noted that this statement was made in the fifties of the present century. However, the present population of the Sinai is 200,000 - Ed.) If a five or six hundred thousand strong army, were to camp there today, it would be quite a task for those at the helm to provide the necessary supplies for the army. Little wonder, then, that many scholars who belive neither in the Scripture nor in miracles, rule out the historical accuracy of the event. For them, the people of Israel camped in an area lying south of Palestine and north of Arabia. In view of the physical and economic geography of the Sinai peninsula, they consider it totally incredible that such a large population could have stayed there for years. What has made these scholars even more sceptical about the event is the fact that the Israelites were not then in a position to procure supplies from either the Egyptians or the 'Amaliqah' who inhabited respectively the eastern and northern parts of the peninsula, since both groups were hostile to them. It is against this background that one may appreciate the immense importance of the favours God conferred on the Israelites. Likewise, it also gives one some idea of the blatant ingratitude of the people of Israel since they consistently defied and betrayed God even though they had witnessed a great many divine signs.
