Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof 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, 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 A token unto them is night. We strip it of the day, and lo! they are in darkness. 37 The sun, too, follows its determined course laid down for it by the Almighty, the All Knowing. 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 Neither is it allowable to the sun that it should overtake the moon, nor can the night outstrip the day; and all float on in a sphere. 40 And a sign for them is that We carried their seed in the laden ship, 41 And We have created for them similar ships, in which they now 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 it be a mercy from Us, and as an enjoyment for a while. 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 And whenever a sign comes to them from the signs of their Lord, they always turn away from it! 46 And when it is said to them, 'Expend of that God has provided you,' the unbelievers say to the believers, 'What, shall we feed such a one whom, if God willed, He would feed? You are only in manifest error!' 47 They also say, 'When shall this promise come to pass, if you speak truly?' 48 They must be waiting for but one single blast, which will overtake them while they are still disputing. 49 Then they cannot make bequest, nor can they return to their own folk. 50
