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 And We have made therein gardens of date-palms and grapes, and We have caused springs of water to gush forth therein. 34 That they may eat of the fruit thereof, and their hands did not make it; will they not then be grateful? 35 Purity is to Him Who created all pairs, from what the earth grows, and of themselves, and from the things they do not know. 36 They have a sign in the night: We withdraw from it the [light of] day -- and they are left in darkness. 37 And the sun runneth on unto a resting-place for him. That is the measuring of the Mighty, the Wise. 38 We have determined the stations of the moon, so that (after its wanderings) it returns as a dried up inflorescent spike of dates. 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 to them is that We bear their offspring in the laden ship. 41 and We have created for them the like of it whereon they ride; 42 And if We will, We can drown them, so there would be no help in their distress, nor would they be saved. 43 unless it be a mercy from us, and as an enjoyment for a season. 44 When they are told, "guard yourselves against what is before you and what is behind you, in order that you may be shown 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 And when they are told, "Spend ye of (the bounties) with which Allah has provided you," the Unbelievers say to those who believe: "Shall we then feed those whom, if Allah had so willed, He would have fed, (Himself)? Ye are in nothing but manifest error." 47 They say, "When will this promise be fulfilled, if you are truthful?" 48 They are only waiting for a single blast that will seize them, but they will go on contending. 49 Then they would not be able to make a will, or go back to their people. 50
