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 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 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 when there came unto them the Truth from Our presence, they said: Why is he not given the like of what was given unto Moses? Did they not disbelieve in that which was given unto Moses of old? They say: Two magics that support each other; and they say: Lo! in both we are disbelievers. 48 Say: 'If what you say is true, bring down from Allah a Book that is a better guidance than both, I will follow it' 49 But if they hearken not to thee, know that they only follow their own lusts: and who is more astray than one who follow his own lusts, devoid of guidance from Allah? for Allah guides not people given to wrong-doing. 50
