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 And you, [O Muhammad], were not on the western side [of the mount] when We revealed to Moses the command, and you were not among the witnesses [to that]. 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 And you were not on this side of the mountain when We called, but a mercy from your Lord that you may warn a people to whom no warner came before you, that they may be mindful. 46 And if (We had) not (sent you to the people of Makkah) in case a calamity should seize them for (the deeds) that their hands have sent forth, they should have said: "Our Lord! Why did You not send us a Messenger? We should then have followed Your Ayat (Verses of the Quran) and should have been 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
