And certainly We gave Musa the Book after We had destroyed the former generations, clear arguments for men and a guidance and a mercy, that they may be mindful. 43 (Prophet Muhammad) you were not on the western side (of the mountain) when We decreed the commandment to Moses, nor were you among those witnessing. 44 But We raised up (new) generations, and long were the ages that passed over them; but thou wast not a dweller among the people of Madyan, rehearsing Our Signs to them; but it is We Who send messengers (with inspiration). 45 And thou was not beside the Mount when We did call; but (the knowledge of it is) a mercy from thy Lord that thou mayst warn a folk unto whom no warner came before thee, that haply they may give heed. 46 Else, did an affliction visit them for that their own hands have forwarded then they might say, 'Our Lord, why didst Thou not send a Messenger to us that we might follow Thy signs and so be among the believers?' 47 But when the truth came to them from Us, they said, "Why was he not given like that which was given to Moses?" Did they not disbelieve in that which was given to Moses before? They said, "[They are but] two works of magic supporting each other, and indeed we are, in both, disbelievers." 48 Say: "Produce, then, [another] revelation from God which would offer better guidance than either of these two [and] I shall follow it, if you speak the truth!" 49 But if they do not answer you, then know that they only follow their low desires; and who is more erring than he who follows his low desires without any guidance from Allah? Surely Allah does not guide the unjust people. 50
