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 We have placed therein gardens of the date-palm and grapes, and We have caused springs of water to gush forth therein, 34 so that they may eat of the fruit thereof, though it was not their hands that made it. Will they not, then, be grateful? 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 strip it of the day and lo, they are in darkness. 37 And the sun runs his course for a period determined for him: that is the decree of (Him), the Exalted in Might, the All-Knowing. 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 39 It is not allowable for the sun to reach the moon, nor does the night overtake the day, but each, in an orbit, is swimming. 40 And a Sign for them is that We bore their race (through the Flood) in the loaded Ark; 41 and We have created for them the like of it whereon 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 Our benevolence, to reap advantage for a time. 44 When it is said to them: 'Have fear of that which is before you and behind you in order that you find mercy' 45 and whenever a revelation out of their Lord's revelations comes to them, they ignore it. 46 And when it is said to them: 'Spend of that which Allah has given you' the unbelievers say to the believers: 'Are we to feed those whom Allah can feed if He chooses? Surely, you are only in clear error' 47 They also say: 'When will this promise be, if what you say is true' 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 Then they cannot make bequest, nor can they return to their own folk. 50
