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 and produced therein grains from which they eat and established therein gardens of palms trees and vineyards and have made streams flow therein 34 that they might eat of its fruits and their hands' labour. What, will they not be thankful? 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 unto them is the night. We draw off the day therefrom, and lo! they are darkened. 37 And the sun runneth to its appointed term: that is the disposition of the Mighty, the Knowing. 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 39 It is not for the sun to overtake the moon, nor does the night outstrip the day. They all float, each in an orbit. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 We have created for them the like of it in which they ride. 42 And if We will, We drown them, and there is no help for them, neither can they be saved; 43 Unless by mercy from Us and as comfort for a while. 44 When they are told, "guard yourselves against what is before you and what is behind you, in order that you may be shown mercy," [they turn away]. 45 Yet there never comes to them any sign of their Lord's signs, but they turn 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 They say, "When will this promise be fulfilled, if you are truthful?" 48 They must be waiting for but one single blast, which will overtake them while they are still disputing. 49 and so [sudden will be their end that] no testament will they be able to make, - nor to their own people will they return! 50
