After destroying the people of the ancient towns We gave the Book to Moses to be a source of knowledge, a guidance, and mercy for mankind so that perhaps they would take heed. 43 And thou (Muhammad) wast not on the western side (of the Mount) when We expounded unto Moses the commandment, and thou wast not among those present; 44 But We produced [many] generations [after Moses], and prolonged was their duration. And you were not a resident among the people of Madyan, reciting to them Our verses, but We were senders [of this message]. 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 and [We have sent thee] lest they say [on Judgment Day,] when disaster befalls them as an outcome of what their own hands have wrought, "O our Sustainer, if only Thou had sent an apostle unto us, we would have followed Thy messages, and would have been 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 do not hearken to this, know well that they only follow their lusts and who is in greater error than he who follows his lusts without any guidance from Allah? Allah does not guide those given to wrong-doing. 50
