And We gave Moses the Book, after We had destroyed the former generations, to be reflections for people and a guidance, and a mercy in order that they might remember. 43 (Muhammad), you were not present at the west bank to witness when We gave the commandments to Moses. 44 But We brought forth generations, and prolonged unto them was life; nor wast thou a dweller among the people of Madyan, reciting unto them Our revelations; but it is We who were to send. 45 And you (O Muhammad SAW) were not at the side of the Tur (Mount) when We did call, [it is said that Allah called the followers of Muhammad SAW, and they answered His Call, or that Allah called Musa (Moses)]. But (you are sent) as a mercy from your Lord, to give warning to a people to whom no warner had come before you, in order that they may remember or receive admonition. [Tafsir At-Tabari, Vol. 20, Page 81]. 46 (We did so) lest a calamity might seize them because of the misdeeds they committed whereafter they would say: "Our Lord, why did you not send a Messenger to us that we follow Your revelation and become among those who believe?" 47 But when the truth came to them from Us, they said: "Why is he not given the like of what was given to Moses?" Did they not disbelieve before in what was given to Moses? They said: "Both are imposters one like the other," and added: "We do not believe in either." 48 Say thou: then bring a Book from before Allah, that is better in guidance than these two, I shall follow it - if ye are truth-tellers. 49 But if they hearken not to thee, know that they only follow their own lusts: and who is more astray than one who follow his own lusts, devoid of guidance from Allah? for Allah guides not people given to wrong-doing. 50
