We did reveal to Moses the Book after We had destroyed the earlier generations, (to give) Insight to men, and guidance and Mercy, that they might receive admonition. 43 You were not present on the western side of the Mount when We gave Our Command to Moses: nor were you among the witnesses, 44 but We raised up generations, and long their lives continued. Neither wast thou a dweller among the Midianites, reciting to them Our signs; but We were sending 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 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 When the Truth from Us came to them they said, "Would that he, (Muhammad), had received what was given to Moses (by his Lord)." Did not they reject what Moses had brought to them saying, "These two, Moses and Aaron, are two magicians who support each other. We do not have any faith in them." 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 So if they do not accept your challenge, then know that they only follow their desires; and who is more astray than one who follows his desires away from the guidance of Allah? Indeed Allah does not guide the unjust. 50
