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 placed therein gardens of palm trees and grapevines and caused to burst forth therefrom some springs - 34 That they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 Hallowed be He who hath created all the pairs of that which the earth groweth, and of themselves and of that which they know not! 36 They have a sign in the night: We withdraw from it the [light of] day -- and they are left 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 We have appointed positions for the moon till it returns like an old branch of the date palm. 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 And a sign for them is that We carried their offspring in the laden Ark (of Noah). 41 And We have created for them similar ships, in which they now ride. 42 We drown them if We will, then they have none to cry to, nor can 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 And never came an Ayah from among the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of their Lord to them, but they did 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 come to pass, if what you say is true?" 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 Then they will be unable to make a will, nor shall they return to their kinsmen. 50
