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 If thou art anxious for their guidance, yet Allah guideth not such as He leaves to stray, and there is none to help them. 37 And they swear by Allah with the most energetic of their oaths: Allah will not raise up him who dies. Yea! it is a promise binding on Him, quite true, but most people do not know; 38 This is in order that He may make clear to them that which they differed upon, and in order that those who disbelieve might know that they were indeed lying. 39 For to anything which We have willed, We but say the word, "Be", and it is. 40
