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 produce therein orchard with date-palms and vines, and We cause springs to gush forth therein: 34 So that they may eat from its fruits, whereas they are not manufactured by their hands! 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 A sign for them is the night. From it We withdraw the day and they are in darkness. 37 And [they have a sign in] the sun: it runs in an orbit of its own [and] that is laid down by the will of the Almighty, 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 how the sun is not supposed to catch-up with the moon, nor is the night to precede the day. All of them are to float in a certain orbit; 40 Another Sign for them is that We carried all their offspring in the laden vessel 41 And We made similar vessels for them to 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 But (by) mercy from Us and for enjoyment till a time. 44 When it is said to them: 'Have fear of that which is before you and behind you in order that you 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 it is said to them, 'Expend of that God has provided you,' the unbelievers say to the believers, 'What, shall we feed such a one whom, if God willed, He would feed? You are only in manifest error!' 47 And they say: when will this promise be fulfilled if ye say sooth? 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 They will have no time to make a will, nor shall they return to their own people. 50
