The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 33 And We placed therein gardens of palm trees and grapevines and caused to burst forth therefrom some springs - 34 So that they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 All glory belongs to the One Who has created pairs out of what grow from the earth, out of their soul and out of that which they do not know. 36 And a sign unto them is the night. We draw off the day therefrom, and lo! they are darkened. 37 And the sun -- it runs to a fixed resting-place; that is the ordaining of the All-mighty, the All-knowing. 38 And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. 39 Neither is it allowable to the sun that it should overtake the moon, nor can the night outstrip the day; and all float on in a sphere. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 And have created for them of the like thereof whereon they ride. 42 Should We so wish, We can drown them, and there will be none to heed their cries of distress, nor will they be rescued. 43 Unless by Our benevolence, to reap advantage for a time. 44 When it is said to such people: “Guard yourselves against what is ahead of you and what has preceded you that mercy be shown to you” (they pay scant heed to it). 45 Not a Sign comes to them from among the Signs of their Lord, but they turn away therefrom. 46 When they are told: "Spend of what God has given you," the unbelievers say to those who believe: "Why should we feed those whom God should have fed if He pleased?" You are only in palpable error. 47 Further, they say, "When will this promise (come to pass), if what ye say is true?" 48 They will not have to wait long. When the Day of Judgment comes, it will only take a single blast of sound to strike them while they are quarrelling with one another. 49 Then they cannot make bequest, nor can they return to their own folk. 50
