After We had destroyed the earlier generations, We gave Moses the Book to give men insight, and as guidance and a blessing for people, so that they might 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 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 in case disaster comes upon them for what they have done themselves, they should say: "O Lord, why did You not send an apostle to us that we should have followed Your commands, and been with those who are 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 If they do not answer you, know that they are only following their desires. And who is further astray than he who is led by his desires without guidance from Allah! Allah does not guide the harmdoers. 50
