Those who associate [others with God] say, "If God had so willed we would not have worshipped anything besides Him, neither we nor our fathers, nor would we have forbidden anything without His sanction." So did those who went before them. The duty of the messengers is only to convey the message clearly. 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 And they swear by Allah their most binding oaths (that) Allah will not raise up him who dieth. Nay, but it is a promise (binding) upon Him in truth, but most of mankind know not, 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 Whenever We will anything to be, We but say unto it Our word "Be" - and it is. 40
