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 And We produce therein orchard with date-palms and vines, and We cause springs to gush forth therein: 34 that they might eat of its fruits. It was not their hands that made them. Will they not, then, give thanks? 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 unto them is the night. We draw off the day therefrom, and lo! they are darkened. 37 While the sun keeps revolving in its orbit. This is the dispensation of the mighty, all-knowing (God). 38 And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. 39 The sun shall not outstrip the moon, nor shall the night outstrip the day. Each is floating in an orbit. 40 how We carried them and their offspring inside the laden Ark 41 And We have created for them of the like thereunto, so on them they ride. 42 If it were Our Will, We could drown them: then would there be no helper (to hear their cry), nor could they be delivered, 43 It is only by Our mercy that they are granted 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 Yet there never comes to them any sign of their Lord's signs, but they turn away from it. 46 and when they are told, "Give to others out of what God has provided for you," those who are bent on denying the truth say to the believers, "Why should we feed those whom God could feed if He wanted? You are clearly in error!" 47 And they say, "When is this promise, if you should be truthful?" 48 They wait not for aught but a single cry which will overtake them while they yet contend with one another. 49 They will have no time to make a will, nor shall they return to their own people. 50
