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 there We made gardens of palms and vines, and in it We caused fountains to gush forth, 34 so that they may eat its fruit, though it was not their hands that made this. Will they not then be grateful? 35 Holy is He who created all things in pairs; of what the earth grows, and of themselves, and other things which they do not know. 36 And a sign to them is the night: We draw forth from it the day, then lo! they are in the dark; 37 And the sun runs [on course] toward its stopping point. That is the determination of the Exalted in Might, the Knowing. 38 how We ordained the moon to pass through certain phases until it seems eventually to be like a bent twig; 39 The sun shall not outstrip the moon, nor shall the night outstrip the day. Each is floating in an orbit. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 And We created for them from the likes of it that which they ride. 42 If it were Our Will, We could drown them: then would there be no helper (to hear their cry), nor could they be delivered, 43 except through Our Mercy and as enjoyment for awhile. 44 But when it is said to them, "Beware of what is before you and what is behind you; perhaps you will receive mercy... " 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 of that with which Allah has provided you," those who disbelieve say to those who believe: "Shall we feed those whom, if Allah willed, He (Himself) would have fed? You are only in a plain error." 47 They also say: 'When will this promise be, if what you say is true' 48 The Truth is that they are waiting for nothing but a mighty Blast to seize them the while they are disputing (in their worldly affairs), 49 Then they will be unable to make a will, nor shall they return to their kinsmen. 50
