The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 33 And We placed therein gardens of palm trees and grapevines and caused to burst forth therefrom some springs - 34 That they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 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 Of the signs for them is how We separated the day from the night and thus they remained 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 [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 It is not for the sun to overtake the moon, nor doth the night outstrip the day. They float each in an orbit. 40 And a sign for them is that We carried their forefathers in a laden ship. 41 And We have created for them similar (vessels) on which they ride. 42 And if We please, We can drown them, then there shall be no succorer for them, nor shall they be rescued 43 unless it be a mercy from us, and as an enjoyment for a season. 44 And when it is said to them, “Beware of what is before you and what is behind you, in the hope of your gaining mercy”, they turn away! 45 And there comes not to them a communication of the communications of their Lord but they turn aside from it. 46 When they are told to spend for the cause of God out of what He has provided for them for their sustenance, the disbelievers say to the believers, "Should we feed those whom God has decided to feed? You are in 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 are only waiting for a single blast that will seize them, but they will go on contending. 49 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
