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 [how] We make gardens of date-palms and vines [grow] thereon, and cause springs to gush [forth] within it, 34 so that they might eat of its fruit and the labor of their hands. Will they not give thanks? 35 Exalted is He who created all pairs - from what the earth grows and from themselves and from that which they do not know. 36 Of the signs for them is how We separated the day from the night and thus they remained in darkness; 37 And the sun runneth to its appointed term: that is the disposition of the Mighty, the Knowing. 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 for the sun to overtake the moon, nor doth the night outstrip the day. They float each in an orbit. 40 And a sign to them is that We bear their offspring in the laden ship. 41 and created for them similar things to ride. 42 Should We so wish, We can drown them, and there will be none to heed their cries of distress, nor will they be rescued. 43 But (by) mercy from Us and for enjoyment till a time. 44 And when it is said to them, 'Fear what is before you and what is behind you; haply you will find mercy' -- 45 and whenever a revelation out of their Lord's revelations comes to them, they ignore 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 And they say: When will this threat come to pass, if you are truthful? 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 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
