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 place therein gardens of the date-palms and vines; and We therein cause to gush forth springs. 34 so that they may consume the fruits and whatever their hands prepare. Will they not then 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 strip it of the day and lo, they are in darkness. 37 The sun is running its course to its appointed place. That is the ordaining of the All-Mighty, the All-Knowing. 38 And the moon, We have measured for it mansions (to traverse) till it returns like the old dried curved 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 Another sign for them is that We carried their offspring in the laden Ark. 41 We have created for them the like of it in which 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 Unless by mercy from Us, and as a 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 yet never any sign of the signs of their Lord comes to them, but they are turning 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 They will not have to wait long. When the Day of Judgment comes, it will only take a single blast of sound to strike them while they are quarrelling with one another. 49 Then they would not be able to make a will, or go back to their people. 50
