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 And We place therein gardens of the date-palms and vines; and We therein cause to gush forth springs. 34 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 unto them is the night. We draw off the day therefrom, and lo! they are darkened. 37 And [they have a sign in] the sun: it runs in an orbit of its own [and] that is laid down by the will of the Almighty, the All-Knowing; 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 39 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 And a sign to them is that We bear their offspring in the laden ship. 41 and then created for them other vessels like those on which 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 It is only Our Mercy (that rescues them) and enables enjoyment of life 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 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 unto them: Spend of that wherewith Allah hath provided you, those who disbelieve say unto those who believe: Shall we feed those whom Allah, if He willed, would feed? Ye are in naught else than error manifest. 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 They will have no time to make a will, nor shall they return to their own people. 50
