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 That then is God, your Lord, the True; what is there, after truth, but error? Then how are you turned about? 32 The decree of your Lord that the evil-doers will not have faith has already been issued. 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: "Of your 'partners' is there any that can give any guidance towards truth?" Say: "It is Allah Who gives guidance towards truth, is then He Who gives guidance to truth more worthy to be followed, or he who finds not guidance (himself) unless he is guided? what then is the matter with you? How judge ye?" 35 Most of them follow nothing except conjecture. But conjecture does not help against the truth. Allah knows the things 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 Do they say: 'He has forged it'. Say: 'Compose one chapter like it, and call upon whom you will, other than Allah (to help you), if what you say is true' 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 And of them is he who believes in it, and of them is he who does not believe in it, and your Lord best knows the mischief-makers. 40
