There is a sign for them in the lifeless earth. We revive it and We produce grain from it of which they eat. 33 And We have placed therein gardens of the date-palm and grapes, and We have caused springs of water to gush forth therein, 34 so that they may consume the fruits and whatever their hands prepare. Will they not then be grateful? 35 Glory be to Him Who created pairs of all things, of what the earth grows, and of their kind and of what they do not know. 36 And a sign for them is the night, We withdraw therefrom the day, and behold, they are 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 We have ordained phases for the moon until finally it becomes like an old date-stalk. 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 That We bore their progeny in the laden ark is a sign for them; 41 And have created for them of the like thereof whereon they ride. 42 And if We should will, We could drown them; then no one responding to a cry would there be for them, nor would they be saved 43 Unless it be a mercy from Us, and as an enjoyment for a while. 44 When it is said unto them: Beware of that which is before you and that which is behind you, that haply ye may find mercy (they are heedless). 45 Never came a token of the tokens of their Lord to them, but they did turn away from it! 46 And when they are told, "Spend ye of (the bounties) with which Allah has provided you," the Unbelievers say to those who believe: "Shall we then feed those whom, if Allah had so willed, He would have fed, (Himself)? Ye are in nothing but manifest error." 47 And they say: "When will this promise (i.e. Resurrection) be fulfilled, if you are truthful?" 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
