And a sign for them is the dead earth; We gave it life and We produced from it grain, so they eat from it. 33 And We have placed therein gardens of the date-palm and grapes, and We have caused springs of water to gush forth therein, 34 That they may eat of His fruit. And their hands have not produced it, so will they not 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 A sign for them is the night. From it We withdraw the day and they are in darkness. 37 And the sun runs his course for a period determined for him: that is the decree of (Him), the Exalted in Might, the All-Knowing. 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 39 Neither is it allowable to the sun that it should overtake the moon, nor can the night outstrip the day; and all float on in a sphere. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 And have created for them of the like thereof whereon they ride. 42 Had We wanted, We could have drowned them and nothing would have been able to help or rescue them 43 But (by) mercy from Us and for enjoyment till a time. 44 When it is said unto them: Beware of that which is before you and that which is behind you, that haply ye may find mercy (they are heedless). 45 Never does any Sign of their Lord come to them, but they turn 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 is this promise, if you should be truthful?" 48 They await but one Shout, which will seize them while they dispute. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
