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 Glory be to Him, who created all the pairs of what the earth produces, and of themselves, and of what they know not. 36 And there is a sign in the night for them. We strip off the day from it and they are left in darkness, 37 And the sun runneth on unto a resting-place for him. That is the measuring of the Mighty, the Wise. 38 And for the moon We have appointed mansions till she return like an old shrivelled palm-leaf. 39 It is not permitted to the sun that it should overtake the moon, nor can the night outstrip the day: each in an orbit, they float. 40 And a sign for them is that We carried their offspring in the laden Ark (of Noah). 41 and [that] We create for them things of a similar kind, on which they may embark [in their travels]; 42 Had We wanted, We could have drowned them and nothing would have been able to help or rescue them 43 Unless by Our benevolence, to reap advantage for a time. 44 And when it is said to them: Guard against what is before you and what is behind you, that mercy may be had on you. 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 from that which Allah has provided for you," those who disbelieve say to those who believe, "Should we feed one whom, if Allah had willed, He would have fed? You are not but in clear error." 47 And they say: "When will this promise come to pass, if what you say is true?" 48 They await but one Shout, which will seize them while they dispute. 49 And they will not be able to make a disposition, nor to their family they return. 50
