(501) And blessed be He unto Whom belongeth the Sovereignty of the heavens and the earth and all that is between them, and with Whom is knowledge of the Hour, and unto Whom ye will be returned.

(502) And those unto whom they cry instead of Him possess no power of intercession, saving him who beareth witness unto the Truth knowingly.

(503) Then bear with them (O Muhammad) and say: Peace. But they will come to know.

(504) A mercy from thy Lord. Lo! He, even He is the Hearer, the knower,

(505) We created them not save with truth; but most of them know not.

(506) And when he knoweth aught of Our revelations he maketh it a jest. For such there is a shameful doom.

(507) And gave them plain commandments. And they differed not until after the knowledge came unto them, through rivalry among themselves. Lo! thy Lord will judge between them on the Day of Resurrection concerning that wherein they used to differ.

(508) And now have We set thee (O Muhammad) on a clear road of (Our) commandment; so follow it, and follow not the whims of those who know not.

(509) And they say: There is naught but our life of the world; we die and we live, and naught destroyeth us save time; when they have no knowledge whatsoever of (all) that; they do but guess.

(510) Say (unto them, O Muhammad): Allah giveth life to you, then causeth you to die, then gathereth you unto the Day of Resurrection whereof there is no doubt. But most of mankind know not.
