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 consume the fruits and whatever their hands prepare. Will they not then be grateful? 35 Hallowed be He who hath created all the pairs of that which the earth groweth, and of themselves and of that which they know not! 36 And a sign for them is the night; We strip it of the day and lo, they are in darkness. 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 And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. 39 The sun cannot overtake the moon, nor can the night outpace the day: each floats in [its own] orbit. 40 And a sign for them is that We carried their seed in the laden ship, 41 We have created for them the like of it in which they ride. 42 We drown them if We will, then they have none to cry to, nor can they be saved, 43 But (by) mercy from Us and for enjoyment till a time. 44 When it is said to such people: “Guard yourselves against what is ahead of you and what has preceded you that mercy be shown to you” (they pay scant heed to it). 45 Indeed, not one of your Lord's signs comes to them without their turning away from it, 46 When they are told to spend for the cause of God out of what He has provided for them for their sustenance, the disbelievers say to the believers, "Should we feed those whom God has decided to feed? You are in plain error." 47 And they say, "When is this promise, if you should be truthful?" 48 They will not have to wait long. When the Day of Judgment comes, it will only take a single blast of sound to strike them while they are quarrelling with one another. 49 and so [sudden will be their end that] no testament will they be able to make, - nor to their own people will they return! 50
