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 (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 neither wert thou present on the slope of Mount Sinai when We called out [to Moses]: but [thou, too, art sent] as an act of thy Sustainer's grace, to warn people to whom no warner has come before thee, so that they might bethink themselves [of Us]; 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 Yet when the truth is come unto them from before Us, they say: wherefore hast he not been vouchsafed the like of that which was given unto Musa? Disbelieved they not in that which was given unto Musa aforetime? They say; two magics supporting each other. And they say: verily in all such things we are disbelievers. 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
