The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 33 And We produce therein orchard with date-palms and vines, and We cause springs to gush forth therein: 34 So that they may eat of its fruit; yet it was not done by their hands. Then why do they not acknowledge thanks? 35 All glory belongs to the One Who has created pairs out of what grow from the earth, out of their soul and out of that which 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 The sun runs to its fixed resting place; that is the decree of the Almighty, the Knower. 38 and [in] the moon, for which We have determined phases [which it must traverse] till it becomes like an old date-stalk, dried-up and curved: 39 It is not permitted to the Sun to catch up the Moon, nor can the Night outstrip the Day: Each (just) swims along in (its own) orbit (according to Law). 40 And a Sign for them is that We bore their race (through the Flood) in the loaded Ark; 41 And We have created for them similar ships, in which they now ride. 42 And if We list, We shall drown them, and there will be no shout for them, nor will they be saved. 43 It is only by Our mercy that they are granted provision for a time. 44 When they are told, "Fear ye that which is before you and that which will be after you, in order that ye may receive Mercy," (they turn back). 45 Not a Sign comes to them from among the Signs of their Lord, but they turn away therefrom. 46 And when they are told, "Spend ye of (the bounties) with which Allah has provided you," the Unbelievers say to those who believe: "Shall we then feed those whom, if Allah had so willed, He would have fed, (Himself)? Ye are in nothing but manifest error." 47 Further, they say, "When will this promise (come to pass), if what ye say is true?" 48 They are awaiting only for one Cry to seize them while they are yet disputing, 49 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
