And a sign for them is the dead earth; We gave it life and We produced from it grain, so they eat from it. 33 We have laid out gardens of dates and grapes upon it, and made springs of water flow, 34 that they might eat of its fruits. It was not their hands that made them. Will they not, then, give thanks? 35 Holy is He who created all things in pairs; of what the earth grows, and of themselves, and other things which they do not know. 36 And a sign unto them is the night. We draw off the day therefrom, and lo! they are darkened. 37 And the sun runs on to a term appointed for it; that is the ordinance of the Mighty, the Knowing. 38 And We have appointed positions for the moon till it returns like an old branch of the date palm. 39 Neither does it lie in the sun's power to overtake the moon nor can the night outstrip the day. All glide along, each in its own orbit. 40 And a sign for them is that We carried their seed in the laden ship, 41 And have created for them of the like thereof whereon 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 It is only by Our mercy that they are granted provision for a time. 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 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 say, "When is this promise, if you should be truthful?" 48 They will not (have to) wait for aught but a single Blast: it will seize them while they are yet disputing among themselves! 49 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
