And a sign for them is the dead land. We gave it life, and We brought forth from it grains, so that they eat thereof. 33 And We produce therein orchard with date-palms and vines, and We cause springs to gush forth therein: 34 so that they may eat its fruit, though it was not their hands that made this. Will they not then be grateful? 35 Glory be to Him Who created pairs of all things, of what the earth grows, and of their kind and of what they do not know. 36 And a sign for them is the night; We strip the day out of it, thereupon they are in darkness. 37 And the sun runs his course for a period determined for him: that is the decree of (Him), the Exalted in Might, the All-Knowing. 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 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 for them is that We lodged them in a laden ship, while they were in their forefathers backs. 41 And have created for them of the like thereof whereon they ride. 42 And if We list, We shall drown them, and there will be no shout for them, nor will they be saved. 43 Unless by mercy from Us and as comfort for a while. 44 When they are told, "Fear ye that which is before you and that which will be after you, in order that ye may receive Mercy," (they turn back). 45 Yet there never comes to them any sign of their Lord's signs, but they turn away from it. 46 and when they are told, "Give to others out of what God has provided for you," those who are bent on denying the truth say to the believers, "Why should we feed those whom God could feed if He wanted? You are clearly in error!" 47 The unbelievers say, "When will the Day of Judgment come if what you say is at all true?" 48 They wait not for aught but a single cry which will overtake them while they yet contend with one another. 49 Therefore neither able to make a will, nor returning to their homes. 50
