There is a sign for them in the lifeless earth. We revive it and We produce grain from it of which they eat. 33 And We place therein gardens of the date-palms and vines; and We therein cause to gush forth springs. 34 That they may eat of the fruit thereof, and their hands did not make it; will they not then be grateful? 35 Glory to Allah, Who created in pairs all things that the earth produces, as well as their own (human) kind and (other) things of which they have no knowledge. 36 And a sign for them is the night, We withdraw therefrom the day, and behold, they are in darkness. 37 And the sun runs [on course] toward its stopping point. That is the determination of the Exalted in Might, the Knowing. 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 39 how the sun is not supposed to catch-up with the moon, nor is the night to precede the day. All of them are to float in a certain orbit; 40 And a Sign for them is that We bore their race (through the Flood) in the loaded Ark; 41 and We have created for them the like of it whereon they ride; 42 And if We will, We drown them, and there is no help for them, neither can they be saved; 43 Except by way of Mercy from Us, and by way of (world) convenience (to serve them) for a time. 44 And when it is said to them: Guard against what is before you and what is behind you, that mercy may be had on you. 45 Never came a token of the tokens of their Lord to them, but they did turn away from it! 46 And when it is said to them: 'Spend of that which Allah has given you' the unbelievers say to the believers: 'Are we to feed those whom Allah can feed if He chooses? Surely, you are only in clear error' 47 They also say, 'When shall this promise come to pass, if you speak truly?' 48 The Truth is that they are waiting for nothing but a mighty Blast to seize them the while they are disputing (in their worldly affairs), 49 then they will not be able to make any testament, nor will they return to their people. 50
