The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 33 We made in it gardens of date-palms and vines, and We caused springs 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 [of Our sway over all that exists] they have a sign in the night: We withdraw from it the [light of] day - and lo! they are 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 determined for it phases, until it returns [appearing] like the old date stalk. 39 Neither does it lie in the sun's power to overtake the moon nor can the night outstrip the day. All glide along, each in its own orbit. 40 And [it ought to be] a sign for them that We bear their offspring [over the seas] in laden ships, 41 and created for them similar things to ride. 42 And if We list, We shall drown them, and there will be no shout for them, nor will they be saved. 43 Unless by Our benevolence, to reap advantage for 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 Indeed, not one of your Lord's signs comes to them without their turning away from it, 46 When they are told: "Spend of what God has given you," the unbelievers say to those who believe: "Why should we feed those whom God should have fed if He pleased?" You are only in palpable error. 47 And they say: "When will this promise come to pass, if what you say is true?" 48 They will not have to wait long. When the Day of Judgment comes, it will only take a single blast of sound to strike them while they are quarrelling with one another. 49 Then they cannot make bequest, nor can they return to their own folk. 50
