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 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 Limitless in His glory is He who has created opposites in whatever the earth produces, and in men's own selves, and in that of which [as yet] they have no knowledge. 36 And a Sign for them is the Night: We withdraw therefrom the Day, and behold they are plunged in darkness; 37 how the sun moves in its orbit and this is the decree of the Majestic and All-knowing God; 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 how the sun is not supposed to catch-up with the moon, nor is the night to precede the day. All of them are to float in a certain orbit; 40 Another sign for them is that We carried their offspring in the laden Ark. 41 And We have created for them similar ships, in which they now 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 save as a mercy from Us, and enjoyment for a while. 44 And [yet,] when they are told, "Beware of [God's insight into] all that lies open before you and all that is hidden from you, so that you might be graced with His mercy," [most men choose to remain deaf;] 45 Indeed, not one of your Lord's signs comes to them without their turning away from it, 46 And when it is said to them: Spend out of what Allah has given you, those who disbelieve say to those who believe: Shall we feed him whom, if Allah please, He could feed? You are in naught but clear error. 47 They also say: 'When will this promise be, if what you say is true' 48 They do not await except one blast which will seize them while they are disputing. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
