And assuredly We vouchsafed the Scripture unto Musa after We had destroyed the generations of old; enlightenment unto mankind and a guidance and a mercy, that haply they might be admonished. 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 and not say, when evil befalls them on account of that which their hands forwarded: 'Our Lord, why did You not send a Messenger to us so that we might follow Your verses and so that we might be among 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 thou: then bring a Book from before Allah, that is better in guidance than these two, I shall follow it - if ye are truth-tellers. 49 Then if they answer thee not, know thou that they only follow their own desires; and who is farther astray than he who followeth his desire without guidance from Allah? Verily Allah guideth not a wrong-doing people. 50
