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 We have placed in it gardens of date palms and vines, and caused springs to gush [forth] from it, 34 so that they might eat of its fruit and the labor of their hands. Will they not 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 withdraw therefrom the day, and behold, they are in darkness. 37 And the sun runneth to its appointed term: that is the disposition of the Mighty, the Knowing. 38 And for the moon We have appointed mansions till she return like an old shrivelled palm-leaf. 39 It is not for the sun to catch up with the moon, nor does the night surpass the day; and each one of them floats in its orbit. 40 And a sign for them is that We carried their seed in the laden ship, 41 And We have created for them of the like thereunto whereon they ride. 42 And if We should will, We could drown them; then no one responding to a cry would there be for them, nor would they be saved 43 except Our mercy which could enable them to enjoy themselves for an appointed time. 44 And when it is said to them, 'Fear what is before you and what is behind you; haply you will find mercy' -- 45 yet never any sign of the signs of their Lord comes to them, but they are turning 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 And they say, "When is this promise, if you should be truthful?" 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
