After We had destroyed the earlier generations We bestowed the Book on Moses - a source of enlightenment for people and a guidance and mercy -- that they may take heed. 43 (Muhammad), you were not present at the west bank to witness when We gave the commandments to Moses. 44 But We brought forth generations, and prolonged unto them was life; nor wast thou a dweller among the people of Madyan, reciting unto them Our revelations; but it is We who were to send. 45 And you were not at the side of the mount when We called [Moses] but [were sent] as a mercy from your Lord to warn a people to whom no warner had come before you that they might be reminded. 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: 'Bring a Book from God that gives better guidance than these, and follow it, if you speak truly.' 49 Then, if they cannot give you an answer, know that they are only following their lusts. And who can be farther astray than he who follows his lust without any guidance from God? And certainly God does not guide an unjust people. 50
