And a sign for them is the dead land, that We quickened and brought forth from it grain, whereof they eat; 33 And We make therein gardens of palms and grapevines and We make springs to flow forth in it, 34 That they may eat of the fruit thereof; and their hands worked it not. Will they not, therefore, 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 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 its course for its final destination; this is a command of the Almighty, the All Knowing. 38 And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. 39 [and] neither may the sun overtake the moon, nor can the night usurp the time of day, since all of them float through space [in accordance with Our laws]. 40 how We carried them and their offspring inside the laden Ark 41 And We have created for them similar ships, in which they now 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 unless it be by an act of mercy from Us and a grant of life for a [further span of] time. 44 When it is said to them: 'Have fear of that which is before you and behind you in order that you find mercy' 45 Not a Sign comes to them from among the Signs of their Lord, but they turn away 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 await but one Shout, which will surprise them while they are disputing. 49 and so [sudden will be their end that] no testament will they be able to make, - nor to their own people will they return! 50
