A Sign for them is the earth that is dead: We do give it life, and produce grain therefrom, of which ye do eat. 33 and [how] We make gardens of date-palms and vines [grow] thereon, and cause springs to gush [forth] within it, 34 That they may eat of the fruit thereof, and their hands made it not. 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 And a sign for them is the night; We strip the day out of it, thereupon they are in darkness. 37 And the sun runneth on unto a resting-place for him. That is the measuring of the Mighty, the Wise. 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 for the sun to catch up with the moon, nor does the night surpass the day; and each one of them floats in its orbit. 40 And a sign for them is that We carried their offspring in the laden Ark (of Noah). 41 And We have created for them the like of it, what they will ride on. 42 If it were Our Will, We could drown them: then would there be no helper (to hear their cry), nor could they be delivered, 43 But (by) mercy from Us and for enjoyment till 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 it is said to them: "Spend of that with which Allah has provided you," those who disbelieve say to those who believe: "Shall we feed those whom, if Allah willed, He (Himself) would have fed? You are only in a plain 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 And they will not be able to make a disposition, nor to their family they return. 50
