And a sign for them is the dead earth. We have brought it to life and brought forth from it grain, and from it they eat. 33 And We make therein gardens of palms and grapevines and We make springs to flow forth in it, 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 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 there is a sign in the night for them. We strip off the day from it and they are left 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 It is not allowable for the sun to reach the moon, nor does the night overtake the day, but each, in an orbit, is swimming. 40 Another Sign for them is that We carried all their offspring in the laden vessel 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 Unless by mercy from Us, and as a comfort for a while. 44 And when it is said to them, 'Fear what is before you and what is behind you; haply you will find mercy' -- 45 None of the signs of their Lord ever comes to them but they turn away from it. 46 And when it is said to them, 'Expend of that God has provided you,' the unbelievers say to the believers, 'What, shall we feed such a one whom, if God willed, He would feed? You are only in manifest error!' 47 They also say, 'When shall this promise come to pass, if you speak truly?' 48 They await but one Shout, which will seize them while they dispute. 49 Then they cannot make bequest, nor can they return to their own folk. 50
