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 Even if you are eager to guide them, God does not surely guide those who have gone astray: They will have no one to help them. 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 so that He may make clear to them that whereon they were at variance, and that the unbelievers may know that they were truly liars. 39 Whenever We will anything to be, We but say unto it Our word "Be" - and it is. 40
