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 And you were not on the western side when We revealed to Musa the commandment, and you were not among the witnesses; 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 If (We had) not (sent thee to the Quraish),- in case a calamity should seize them for (the deeds) that their hands have sent forth, they might say: "Our Lord! why didst Thou not sent us a messenger? We should then have followed Thy Signs and been amongst those who believe!" 47 But (now), when the Truth has come to them from Ourselves, they say, "Why are not (Signs) sent to him, like those which were sent to Moses?" Do they not then reject (the Signs) which were formerly sent to Moses? They say: "Two kinds of sorcery, each assisting the other!" And they say: "For us, we reject all (such things)!" 48 Say: "Then bring a Book from God which gives better guidance than these so that I may follow it, if you speak the truth." 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
