Those who associate others with Allah in His Divinity say: "Were Allah to will so, neither we nor our forefathers would have worshipped any other than Him, nor would we have prohibited anything without His command." Their predecessors proffered similar excuses. Do the Messengers have any other duty but to plainly convey the Message? 35 We sent a Messenger to every nation, saying: 'Worship Allah and avoid the idols' Amongst them were some whom Allah guided, and some justly disposed to error. Travel in the land and see what was the end of those who belied (the Revelation and the prophets)! 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 their strongest oaths [that] Allah will not resurrect one who dies. But yes - [it is] a true promise [binding] upon Him, but most of the people do not know. 38 In order that He may make manifest to them the truth of that wherein they differ, and that those who disbelieved (in Resurrection, and in the Oneness of Allah) may know that they were liars. 39 When We decree a thing, We only say: 'Be' and it is. 40
