The idolaters say: "If God had willed we would not have worshipped anything apart from Him, nor would our fathers have done, nor would we have forbidden any thing without His (leave)." So had the people done before them. Therefore it is binding on the prophets to convey the message in clearest terms. 35 To every community We have sent an apostle. (saying:) "Worship God, and keep away from all other deities." Thus some of them were guided by God, and ruin was justified on some. Travel over the earth and see what befell those who accused (the apostles) of lies. 36 [As for those who are bent on denying the truth - ] though thou be ever so eager to show them the right way, [know that,] verily, God does not bestow His guidance upon any whom He judges to have gone astray; and such shall have none to succour them [on Resurrection Day]. 37 They swear their strongest oaths by God that God will never raise the dead to life -- nonetheless, it is a promise truly binding on Him, even though most people do not realize it -- 38 For (they fear) He might make what they differed about plain to them, and that the infidels may realise that they were liars. 39 Indeed, Our word to a thing when We intend it is but that We say to it, "Be," and it is. 40
