And a sign for them is the dead land, that We quickened and brought forth from it grain, whereof they eat; 33 and We made therein gardens of palms and vines, and therein We caused fountains to gush forth, 34 That they may eat of His fruit. And their hands have not produced it, so will they not be grateful? 35 Purity is to Him Who created all pairs, from what the earth grows, and of themselves, and from the things they do not know. 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 on to a term appointed for it; that is the ordinance of the Mighty, the Knowing. 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 39 The sun shall not outstrip the moon, nor shall the night outstrip the day. Each is floating in an orbit. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 and then created for them other vessels like those on which they ride. 42 And if We please, We can drown them, then there shall be no succorer for them, nor shall they be rescued 43 Except as a mercy from Us and provision for 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 None of the signs of their Lord ever comes to them but they turn away from it. 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 And they say: "When will this promise come to pass, if what you say is true?" 48 They will not (have to) wait for aught but a single Blast: it will seize them while they are yet disputing among themselves! 49 Then they will not be able to make bequest, nor they will return to their family. 50
