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 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, whether it be of what the earth produces, and of themselves, and of what they do not know. 36 And a sign for them is the night; We strip it of the day and lo, they are 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 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 doth the night outstrip the day. They float each in an orbit. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 And We have created for them the like of it in which they board. 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 But (by) mercy from Us and for enjoyment till a time. 44 And when it is said to them: Guard against what is before you and what is behind you, that mercy may be had on you. 45 and no message of their Sustainer's messages ever reaches them without their turning away from it. 46 And when it is said unto them: Spend of that wherewith Allah hath provided you, those who disbelieve say unto those who believe: Shall we feed those whom Allah, if He willed, would feed? Ye are in naught else than error manifest. 47 And they say: When will this threat come to pass, if you are truthful? 48 They will not (have to) wait for aught but a single Blast: it will seize them while they are yet disputing among themselves! 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
