And a sign for them is the dead earth. We have brought it to life and brought forth from it grain, and from it they eat. 33 and We made therein gardens of palms and vines, and therein We caused fountains to gush forth, 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 Holy is He Who created all things in pairs, whether it be of what the earth produces, and of themselves, and of what they do not know. 36 A sign for them is the night. From it We withdraw the day and they are in darkness. 37 And the sun runs on its fixed course for a term (appointed). That is the Decree of the All-Mighty, the All-Knowing. 38 And the Moon,- We have measured for her mansions (to traverse) till she returns like the old (and withered) lower part of a date-stalk. 39 The sun shall not outstrip the moon, nor shall the night outstrip the day. Each is floating in an orbit. 40 And a token unto them is that We bear their offspring in the laden ship, 41 And have created for them of the like thereof whereon they ride. 42 And if We list, We shall drown them, and there will be no shout for them, nor will they be saved. 43 Unless by Our benevolence, to reap advantage for a time. 44 When they are told, "Fear ye that which is before you and that which will be after you, in order that ye may receive Mercy," (they turn back). 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 Further, they say, "When will this promise (come to pass), if what ye say is true?" 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 they will not be able [to give] any instruction, nor to their people can they return. 50
