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 You were not there on the western side (of Mount Sinai) when We gave the commandments to Moses, nor were you witness (to the event). 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 you were not on the side of the Mount when We called out to Moses, but We have sent you as a mercy from your Lord, so that you may warn people to whom no warner has been sent before you, so that they may take heed, 46 Otherwise, if disaster should afflict them because of that which their own hands have sent before (them), they might say: Our Lord! Why sentest Thou no messenger unto us, that we might have followed Thy revelations and been of the believers? 47 But when the truth came to them from Us, they said, "Why has he not been given the like of what Moses was given?" But did they not reject what Moses was given before? They said, "Both [Moses and Muhammad] are kinds of sorcery, each assisting the other." And they add, "We reject both of them." 48 Say to them, "Bring down from God a scripture that is a better guide than these two and I will follow it, if what you say be true." 49 If they cannot meet such a challenge, know that they are only following their (evil) desires. Who strays more than one who follows his desires without guidance from God? God does not guide the unjust people. 50
