The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 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, though it was not their hands that made it. Will they not, then, be grateful? 35 Exalted is He who created all pairs - from what the earth grows and from themselves and from that which 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 The sun is running its course to its appointed place. That is the ordaining of the All-Mighty, the All-Knowing. 38 And for the moon We have appointed mansions till she return like an old shrivelled palm-leaf. 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 lodged them in a laden ship, while they were in their forefathers backs. 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 Except by way of Mercy from Us, and by way of (world) convenience (to serve them) for a time. 44 When it is said to them: "Beware of what is before you and what is past, that you may be treated with kindness;" 45 and no message of their Sustainer's messages ever reaches them without their turning 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 And they add, "When is this promise [of resurrection] to be fulfilled? [Answer this] if you are men of truth!" 48 They do not await except one blast which will seize them while they are disputing. 49 Therefore neither able to make a will, nor returning to their homes. 50
