And they who give associates (to Allah) say: If Allah had pleased, we would not have served anything besides Allah, (neither) we nor our fathers, nor would we have prohibited anything without (order from) Him. Thus did those before them; is then aught incumbent upon the apostles except a plain delivery (of the message)? 35 And We certainly sent into every nation a messenger, [saying], "Worship Allah and avoid Taghut." And among them were those whom Allah guided, and among them were those upon whom error was [deservedly] decreed. So proceed through the earth and observe how was the end of the deniers. 36 Though thou art ever so eager to guide them, God guides not those whom He leads astray; they have no helpers. 37 They swear their strongest oaths by Allah, that Allah will not raise up those who die: Nay, but it is a promise (binding) on Him in truth: but most among mankind realise it 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 When We decree a thing, We only say: 'Be' and it is. 40
