And a sign for them is the dead land. We gave it life, and We brought forth from it grains, so that they eat thereof. 33 We made in it gardens of date-palms and vines, and We caused springs to gush forth 34 so that they might eat of its fruit and the labor of their hands. Will they not give thanks? 35 Glory be to Him Who created all the sexual 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 withdraw therefrom the Day, and behold they are plunged 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 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 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 all their offspring in the laden vessel 41 And have created for them of the like thereof whereon they ride. 42 and [that,] if such be Our will, We may cause them to drown, with none to respond to their cry for help: and [then] they cannot be saved, 43 Unless by mercy from Us and as comfort for a while. 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 And not a sign cometh unto them of the signs of their Lord, but they are ever backsliders therefrom. 46 And when it is said to them: 'Spend of that which Allah has given you' the unbelievers say to the believers: 'Are we to feed those whom Allah can feed if He chooses? Surely, you are only in clear error' 47 They also say, 'When shall this promise come to pass, if you speak truly?' 48 They await but one Shout, which will seize them while they dispute. 49 then they will not be able to make any testament, nor will they return to their people. 50
