Evidence (of the truth) for them is how We revived the dead earth 33 And We placed therein gardens of palm trees and grapevines and caused to burst forth therefrom some springs - 34 That they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 Holy is He who created all things in pairs; of what the earth grows, and of themselves, and other things which they do not know. 36 And a Sign for them is the Night: We withdraw therefrom the Day, and behold they are plunged in darkness; 37 And the sun runs [on course] toward its stopping point. That is the determination of the Exalted in Might, the Knowing. 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 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 Another sign for them is that We carried their offspring in the laden Ark. 41 And We have created for them similar ships, in which they now ride. 42 If it were Our will, We could drown them: then there would be no helper [to hear their cry], nor could they be saved. 43 except through Our Mercy and as enjoyment for awhile. 44 And when it is said unto them: fear that which is before you and that which is behind you, that haply ye may find mercy, they withdraw. 45 And not a sign cometh unto them of the signs of their Lord, but they are ever backsliders therefrom. 46 And when it is said to them: 'Spend of that which Allah has given you' the unbelievers say to the believers: 'Are we to feed those whom Allah can feed if He chooses? Surely, you are only in clear error' 47 And they say: When will this threat come to pass, if you are truthful? 48 They do not await except one blast which will seize them while they are disputing. 49 Then they will be unable to make a will, nor shall they return to their kinsmen. 50
