And a sign unto them is the dead land. We quicken it and thereout We bring forth grain, so that thereof they eat. 33 And We have made therein gardens of date-palms and grapes, and We have caused springs of water to gush forth therein. 34 So that they may eat of its fruit; yet it was not done by their hands. Then why do they not acknowledge thanks? 35 Holy is He Who created all things in pairs, whether it be of what the earth produces, and of themselves, and of what 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 - We have determined for it phases, until it returns [appearing] like the 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 Another sign for them is that We carried their offspring in the laden Ark. 41 And have created for them of the like thereof whereon they ride. 42 We could have drowned them if We pleased, and none would have answered their cry for help, nor would they have been saved, 43 Unless by Our benevolence, to reap advantage for a time. 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 does any Sign of their Lord come to them, but they turn away from it. 46 When they are told to spend for the cause of God out of what He has provided for them for their sustenance, the disbelievers say to the believers, "Should we feed those whom God has decided to feed? You are in plain error." 47 And they say: When will this threat come to pass, if you are truthful? 48 They await but one Shout, which will seize them while they dispute. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
