There is a sign for them in the lifeless earth. We revive it and We produce grain from it of which they eat. 33 and We made therein gardens of palms and vines, and therein We caused fountains to gush forth, 34 So that they may eat of the fruit thereof, and their hands made it not. Will they not, then, 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 remove from it [the light of] day, so they are [left] in darkness. 37 And the sun runneth to its appointed term: that is the disposition of the Mighty, the Knowing. 38 And the moon, We have measured for it mansions (to traverse) till it returns like the old dried curved date stalk. 39 It is not for the sun to overtake the moon, nor does the night outstrip the day. They all float, each in an orbit. 40 And a token unto them is that We bear their offspring in the laden ship, 41 and [that] We create for them things of a similar kind, on which they may embark [in their travels]; 42 We drown them if We will, then they have none to cry to, nor can they be saved, 43 It is only by Our mercy that they are granted provision for a time. 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 Indeed, not one of your Lord's signs comes to them without their 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 will this promise (i.e. Resurrection) be fulfilled, if you are truthful?" 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 Then they cannot make bequest, nor can they return to their own folk. 50
