Say (unto them, O Muhammad): Who provideth for you from the sky and the earth, or Who owneth hearing and sight; and Who bringeth forth the living from the dead and bringeth forth the dead from the living; and Who directeth the course? They will say: Allah. Then say: Will ye not then keep your duty (unto Him)? 31 Such is Allah, your real Cherisher and Sustainer: apart from truth, what (remains) but error? How then are ye turned away? 32 Thus the word of thy Lord is realized against the ungodly that they believe not. 33 Say, "Are there of your 'partners' any who begins creation and then repeats it?" Say, "Allah begins creation and then repeats it, so how are you deluded?" 34 Ask them: 'Are there among ones whom you associate with Allah in His divinity those who can guide to the truth? Say: 'It is Allah alone Who guides to the truth.' Then, who is more worthy to be followed - He Who guides to the truth, or he who cannot find the right way unless others guide him to it? What is wrong with you? How ill do you judge! 35 And the most of them follow only surmise, and surmise avails naught against truth. Surely God knows the things they do. 36 This Qur'an is not such (a writ) as could be composed by anyone but God. It confirms what has been revealed before, and is an exposition of (Heaven's) law. Without any doubt it's from the Lord of all the worlds. 37 Or do they say [about the Prophet], "He invented it?" Say, "Then bring forth a surah like it and call upon [for assistance] whomever you can besides Allah, if you should be truthful." 38 Rather, they have denied that which they encompass not in knowledge and whose interpretation has not yet come to them. Thus did those before them deny. Then observe how was the end of the wrongdoers. 39 And of them are those who believe in it, and of them are those who do not believe in it. And your Lord is most knowing of the corrupters 40
