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 placed therein gardens of palm trees and grapevines and caused to burst forth therefrom some springs - 34 so that they might eat of its fruit and the labor of their hands. Will they not give thanks? 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 The sun, too, follows its determined course laid down for it by the Almighty, the All Knowing. 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 39 It is not for the sun to overtake the moon, nor does the night outstrip the day. They all 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 created for them similar things to 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 Except as a mercy from Us and provision for 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 And not a sign cometh unto them of the signs of their Lord, but they are ever backsliders therefrom. 46 When they are told to spend for the cause of God out of what He has provided for them for their sustenance, the disbelievers say to the believers, "Should we feed those whom God has decided to feed? You are in plain error." 47 And they say: When will this threat come to pass, if you are truthful? 48 They will not have to wait long. When the Day of Judgment comes, it will only take a single blast of sound to strike them while they are quarrelling with one another. 49 Then they cannot make bequest, nor can they return to their own folk. 50
