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 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 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 you were not on this side of the mountain when We called, but a mercy from your Lord that you may warn a people to whom no warner came before you, that they may be mindful. 46 And were it not that there should befall them a disaster for what their hands have sent before, then they should say: Our Lord! why didst Thou not send to us an apostle so that we should have followed Thy communications and been of the believers! 47 When the Truth from Us came to them they said, "Would that he, (Muhammad), had received what was given to Moses (by his Lord)." Did not they reject what Moses had brought to them saying, "These two, Moses and Aaron, are two magicians who support each other. We do not have any faith in them." 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 So if they do not accept your challenge, then know that they only follow their desires; and who is more astray than one who follows his desires away from the guidance of Allah? Indeed Allah does not guide the unjust. 50
