After We had destroyed the earlier generations We gave Moses the Book as evidence for mankind, and a guidance and grace, so that they may remember. 43 And thou wast not on the western side when We decreed the affair unto Musa, and thou wast not of the witnesses. 44 We brought into being many generations who lived long lives, nor did you live among the people of Midian and recite our revelations to them, it is We who send messengers, 45 And nor were you beside the Mount when We proclaimed – however it is a mercy from your Lord* so that you may warn a nation towards whom no Herald of Warning came before you, in the hope of their heeding advice. (*That He has bestowed knowledge of the hidden to you) 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 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: "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 But if they do not answer you, then know that they only follow their low desires; and who is more erring than he who follows his low desires without any guidance from Allah? Surely Allah does not guide the unjust people. 50
