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 make therein gardens of palms and grapevines and We make springs to flow forth in it, 34 So that they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 Holy is He Who created all things in pairs, whether it be of what the earth produces, and of themselves, and of what they do not know. 36 And a sign for them is the night. We remove from it [the light of] day, so they are [left] 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 determined the stations of the moon, so that (after its wanderings) it returns as a dried up inflorescent spike of dates. 39 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 And a Sign for them is that We bore their race (through the Flood) in the loaded Ark; 41 We have created for them the like of it in which they ride. 42 If it were Our will, We could drown them: then there would be no helper [to hear their cry], nor could 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 Never does any Sign of their Lord come to them, but they turn away from it. 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 Further, they say, "When will this promise (come to pass), if what ye say is true?" 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 Then they will be unable to make a will, nor shall they return to their kinsmen. 50
