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 Thus is God your true Lord. In the absence of truth there is nothing but falsehood. Then where are you turning? 32 Thus the word of your Lord about those who disobey comes true, that they do not believe. 33 Ask them: "Is there among the partners (you ascribe to God) one who first originates then reverts it? Say: "It is God alone who first creates and then reverts it. So where do you stray?" 34 Say, "Are there of your 'partners' any who guides to the truth?" Say, "Allah guides to the truth. So is He who guides to the truth more worthy to be followed or he who guides not unless he is guided? Then what is [wrong] with you - how do you judge?" 35 Most of them only follow conjectures; and surely conjecture can be no substitute for truth. Allah is well aware of whatever they do. 36 Now this Qur'an could not possibly have been devised by anyone save God: nay indeed, it confirms the truth of whatever there still remains [of earlier revelations] and clearly spells out the revelation [which comes] - let there be no doubt about it - from the Sustainer of all the worlds. 37 Or do they say: He has forged it? Say: Then bring a chapter like this and invite whom you can besides Allah, if you are truthful. 38 No; but they have cried lies to that whereof they comprehended not the knowledge, and whose interpretation has not yet come to them. Even so those that were before them cried lies; then behold how was the end of the evildoers! 39 Of them there are some who believe therein, and some who do not: and thy Lord knoweth best those who are out for mischief. 40
