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 there We made gardens of palms and vines, and in it We caused fountains to gush forth, 34 so that they might eat of its fruit and the labor of their hands. Will they not 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 They have a sign in the night: We withdraw from it the [light of] day -- and they are left in darkness. 37 And the sun runneth to its appointed term: that is the disposition of the Mighty, the Knowing. 38 And the moon! For it We have decreed mansions till it reverteth like the old branch of a palm-tree. 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 We have created for them the like of it whereon they ride; 42 And if We list, We shall drown them, and there will be no shout for them, nor will they be saved. 43 Unless by Our benevolence, to reap advantage for a time. 44 When it is said to such people: “Guard yourselves against what is ahead of you and what has preceded you that mercy be shown to you” (they pay scant heed to it). 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: "Spend of that with which Allah has provided you," those who disbelieve say to those who believe: "Shall we feed those whom, if Allah willed, He (Himself) would have fed? You are only in a plain error." 47 And they say: when will this promise be fulfilled if ye say sooth? 48 [And they are unaware that] nothing awaits them beyond a single blast [of God's punishment,] which will overtake them while they are still arguing - [against resurrection]: 49 Therefore neither able to make a will, nor returning to their homes. 50
