And a sign for them is the dead earth; We gave it life and We produced from it grain, so they eat from it. 33 And We make therein gardens of palms and grapevines and We make springs to flow forth in it, 34 so that they may eat its fruit, though it was not their hands that made this. Will they not then be grateful? 35 Purity is to Him Who created all pairs, from what the earth grows, and of themselves, and from the things they do not know. 36 And a sign to them is the night: We draw forth from it the day, then lo! they are in the dark; 37 The sun runs to its fixed resting place; that is the decree of the Almighty, the Knower. 38 and [in] the moon, for which We have determined phases [which it must traverse] till it becomes like an old date-stalk, dried-up and curved: 39 It is not permitted to the Sun to catch up the Moon, nor can the Night outstrip the Day: Each (just) swims along in (its own) orbit (according to Law). 40 That We bore their progeny in the laden ark is a sign for them; 41 and then created for them other vessels like those on which they ride. 42 And if We list, We shall drown them, and there will be no shout for them, nor will they be saved. 43 unless it be a mercy from us, and as an enjoyment for a season. 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 And when it is said to them, 'Expend of that God has provided you,' the unbelievers say to the believers, 'What, shall we feed such a one whom, if God willed, He would feed? You are only in manifest error!' 47 And they say, "When is this promise, if you should be truthful?" 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 Then they cannot make bequest, nor can they return to their own folk. 50
