The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 33 And there We made gardens of palms and vines, and in it We caused fountains to gush forth, 34 so that they may consume the fruits and whatever their hands prepare. Will they not then be grateful? 35 All glory to Him who created pairs of everything that grows from the earth, and out of themselves, and other things they do not know. 36 A token unto them is night. We strip it of the day, and lo! they are in darkness. 37 And [they have a sign in] the sun: it runs in an orbit of its own [and] that is laid down by the will of the Almighty, the All-Knowing; 38 We have ordained phases for the moon until finally it becomes like an old date-stalk. 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 lodged them in a laden ship, while they were in their forefathers backs. 41 and We have created for them the like of it whereon they ride; 42 If it were Our Will, We could drown them: then would there be no helper (to hear their cry), nor could they be delivered, 43 But (by) mercy from Us and for enjoyment till a time. 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 yet never any sign of the signs of their Lord comes to them, but they are turning away from it. 46 And when it is said to them, "Spend from that which Allah has provided for you," those who disbelieve say to those who believe, "Should we feed one whom, if Allah had willed, He would have fed? You are not but in clear error." 47 Further, they say, "When will this promise (come to pass), if what ye say is true?" 48 They await just one scream, which will overcome them while they are involved in worldly disputes. 49 and they will not even be able to make a testament, nor to return to their households. 50
