And a sign for them is the dead land, that We quickened and brought forth from it grain, whereof they eat; 33 And We place therein gardens of the date-palms and vines; and We therein cause to gush forth springs. 34 So that they may eat of its fruit; yet it was not done by their hands. Then why do they not acknowledge thanks? 35 Exaltations to Him who created pairs of all the things the earth produces and of themselves, and that of which they have no knowledge. 36 And a sign for them is the night; We strip the day out of it, thereupon they are in darkness. 37 The sun, too, follows its determined course laid down for it by the Almighty, the All Knowing. 38 And the moon -- We have determined it by stations, till it returns like an aged palm-bough. 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 token unto them is that We bear their offspring in the laden ship, 41 And We made similar vessels for them to 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 It is only Our Mercy (that rescues them) and enables enjoyment of life for a while. 44 When it is said unto them: Beware of that which is before you and that which is behind you, that haply ye may find mercy (they are heedless). 45 None of the signs of their Lord ever comes to them but they turn away from it. 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 promise be fulfilled if ye say sooth? 48 They await but one Shout, which will seize them while they dispute. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
