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 laid out gardens of dates and grapes upon it, and made springs of water flow, 34 That they may eat of His fruit. And their hands have not produced it, so will they not be grateful? 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 withdraw therefrom the Day, and behold they are plunged in darkness; 37 While the sun keeps revolving in its orbit. This is the dispensation of the mighty, all-knowing (God). 38 And the moon, We have measured for it mansions (to traverse) till it returns like the old dried curved 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 a token unto them is that We bear their offspring in the laden ship, 41 And We have created for them of the like thereunto whereon they ride. 42 If it were Our will, We could drown them: then there would be no helper [to hear their cry], nor could they be saved. 43 Unless by mercy from Us, and as a comfort for a while. 44 When it is said unto them: Beware of that which is before you and that which is behind you, that haply ye may find mercy (they are heedless). 45 Never came a token of the tokens of their Lord to them, but they did turn away from it! 46 And when it is said to them, “Spend in Allah’s cause, from what Allah has provided you”, the disbelievers say regarding the believers, “Shall we feed these, whom if Allah willed, would have fed? You are not but in open 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 for aught but a single Blast: it will seize them while they are yet disputing among themselves! 49 Therefore neither able to make a will, nor returning to their homes. 50
