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 NOW [as for thee, O Muhammad,] thou wert not present on the sunset slope [of Mount Sinai] when We imposed the Law upon Moses, nor wert thou among those who witnessed [his times]: 44 We raised (many more) generations and prolonged their lives. You did not live with the people of Midian, nor recited to them Our revelations; but We kept on sending messengers. 45 You were not present on the side of the Tor when We called. Yet as a mercy from your Lord to warn a nation to whom no warner has been sent before, in order that they remember 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 (now), when the Truth has come to them from Ourselves, they say, "Why are not (Signs) sent to him, like those which were sent to Moses?" Do they not then reject (the Signs) which were formerly sent to Moses? They say: "Two kinds of sorcery, each assisting the other!" And they say: "For us, we reject all (such things)!" 48 Say: Then bring some (other) book from Allah which is a better guide than both of them, (that) I may follow it, if you are truthful. 49 But if they do not hearken to this, know well that they only follow their lusts and who is in greater error than he who follows his lusts without any guidance from Allah? Allah does not guide those given to wrong-doing. 50
