(23) The (material) things which ye are given are but the conveniences of this life and the glitter thereof; but that which is with Allah is better and more enduring: will ye not then be wise?

(24) And We have left thereof an evident Sign, for any people who (care to) understand.

(25) It is Allah Who sends the Winds, and they raise the Clouds: then does He spread them in the sky as He wills, and break them into fragments, until thou seest rain-drops issue from the midst thereof: then when He has made them reach such of his servants as He wills behold, they do rejoice!-

(26) Men ask thee concerning the Hour: Say, "The knowledge thereof is with Allah (alone)": and what will make thee understand?- perchance the Hour is nigh!

(28) He knows all that goes into the earth, and all that comes out thereof; all that comes down from the sky and all that ascends thereto and He is the Most Merciful, the Oft-Forgiving.

(29) On account of their arrogance in the land and their plotting of Evil, but the plotting of Evil will hem in only the authors thereof. Now are they but looking for the way the ancients were dealt with? But no change wilt thou find in Allah's way (of dealing): no turning off wilt thou find in Allah's way (of dealing).

(30) "Is not He Who created the heavens and the earth able to create the like thereof?" - Yea, indeed! for He is the Creator Supreme, of skill and knowledge (infinite)!
