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 seeing that He is God, your Sustainer, the Ultimate Truth? For, after the truth [has been forsaken,] what is there [left] but error? How, then, can you lose sight of the truth?" 32 The decree of your Lord that the evil-doers will not have faith has already been issued. 33 Say: 'Is there any of your associates who originates creation, then brings it back again?' Say: 'God -- He originates creation, then brings it back again; so how are you perverted?' 34 Say: 'Is there any of your associates who guides to the truth?' Say: 'God -- He guides to the truth; and which is worthier to be followed -- He who guides to the truth, or he who guides not unless he is guided? What then ails you, how you judge?' 35 Most of them follow nothing but mere conjecture. But conjecture is of no use against the Truth. God is well aware of what they do. 36 No one could have composed this Quran besides God. This confirms the existing Book (the Bible) and explains itself. There is no doubt that it is from the Lord of the Universe. 37 Or do they say, 'Why, he has forged it'? Say: 'Then produce a sura like it, and call on whom you can, apart from God, if you speak truly.' 38 On the contrary, they denied the thing the knowledge of which they could not master, whereas they have not yet seen its outcome; similarly those before them had denied, therefore see what sort of fate befell the unjust! 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
