The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 33 and We made therein gardens of palms and vines, and therein We caused fountains to gush forth, 34 That they may eat of the fruit thereof; and their hands worked it not. Will they not, therefore, 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 for them is the Night: We withdraw therefrom the Day, and behold they are plunged in darkness; 37 And the sun -- it runs to a fixed resting-place; that is the ordaining of the All-mighty, the All-knowing. 38 And the moon -- We have determined it by stations, till it returns like an aged palm-bough. 39 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 And a sign unto them is that We bear their offspring in a laden ship. 41 And have created for them of the like thereof whereon they ride. 42 We could have drowned them if We pleased, and none would have answered their cry for help, nor would they have been saved, 43 Except by way of Mercy from Us, and by way of (world) convenience (to serve them) for a time. 44 And [yet,] when they are told, "Beware of [God's insight into] all that lies open before you and all that is hidden from you, so that you might be graced with His mercy," [most men choose to remain deaf;] 45 Never does any Sign of their Lord come to them, but they 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 And they say: When will this threat come to pass, if you are truthful? 48 They wait not for aught but a single cry which will overtake them while they yet contend with one another. 49 Then they will not be able to make bequest, nor they will return to their family. 50
