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 And thou wast not on the western side when We decreed the affair unto Musa, and thou wast not of the witnesses. 44 But We raised many generations after Moses and they lived for many years. You did not dwell with the people of Midian reciting Our revelations to them, but We had certainly sent Messengers to them. 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 If (We had) not (sent thee to the Quraish),- in case a calamity should seize them for (the deeds) that their hands have sent forth, they might say: "Our Lord! why didst Thou not sent us a messenger? We should then have followed Thy Signs and been amongst those who believe!" 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 (unto them, O Muhammad): Then bring a scripture from the presence of Allah that giveth clearer guidance than these two (that) I may follow it, if ye 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
