There is a sign for them in the lifeless earth. We revive it and We produce grain from it of which they eat. 33 and We made therein gardens of palms and vines, and therein We caused fountains to gush forth, 34 that they might eat of its fruits. It was not their hands that made them. Will they not, then, give thanks? 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 A sign for them is the night. From it We withdraw the day and they are in darkness. 37 And the sun runs [on course] toward its stopping point. That is the determination of the Exalted in Might, the Knowing. 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 39 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 how We carried them and their offspring inside the laden Ark 41 And We have created for them the like of it in which they board. 42 and [that,] if such be Our will, We may cause them to drown, with none to respond to their cry for help: and [then] they cannot be saved, 43 Unless by Our benevolence, to reap advantage for a time. 44 When it is said unto them: Beware of that which is before you and that which is behind you, that haply ye may find mercy (they are heedless). 45 And not a sign cometh unto them of the signs of their Lord, but they are ever backsliders therefrom. 46 and when they are told, "Give to others out of what God has provided for you," those who are bent on denying the truth say to the believers, "Why should we feed those whom God could feed if He wanted? You are clearly in error!" 47 And they add, "When is this promise [of resurrection] to be fulfilled? [Answer this] if you are men of truth!" 48 They do not await except one blast which will seize them while they are disputing. 49 And they will not be able to make a disposition, nor to their family they return. 50
