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 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 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 Nor were you on the side of the Mount (Sinai) when We called out to Moses (in the first instance). But it is out of Mercy from your Lord (that you are being informed of all this) so that you may warn a people to whom no warner came before you. Maybe they will take heed. 46 And in case disaster comes upon them for what they have done themselves, they should say: "O Lord, why did You not send an apostle to us that we should have followed Your commands, and been with those who are believers;" 47 But (now) when the truth has come to them from Us, they say: Why is he not given the like of what was given to Musa? What! did they not disbelieve in what Musa was given before? They say: Two magicians backing up each other; and they say: Surely we are unbelievers in all. 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 Then if they answer thee not, know thou that they only follow their own desires; and who is farther astray than he who followeth his desire without guidance from Allah? Verily Allah guideth not a wrong-doing people. 50
