And a sign for them is the dead land. We gave it life, and We brought forth from it grains, so that they eat thereof. 33 We made in it gardens of date-palms and vines, and We caused springs to gush forth 34 So 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 withdraw therefrom the day, and behold, 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 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 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 token unto them is that We bear their offspring in the laden ship, 41 and created for them similar things to ride. 42 We could have drowned them if We pleased, and none would have answered their cry for help, nor would they have been 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 yet never any sign of the signs of their Lord comes to them, but they are turning away from it. 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 are only waiting for a single blast that will seize them, but they will go on contending. 49 And they will not be able to make a disposition, nor to their family they return. 50
