Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 And We make therein gardens of palms and grapevines and We make springs to flow forth in it, 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 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 A sign for them is the night. From it We withdraw the day and they are in darkness. 37 And the sun runs its course for its final destination; this is a command of the Almighty, the All Knowing. 38 And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. 39 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 And a token unto them is that We bear their offspring in the laden ship, 41 We have created for them the like of it in which 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 it be by an act of mercy from Us and a grant of life for a [further span of] time. 44 And when it is said unto them: fear that which is before you and that which is behind you, that haply ye may find mercy, they withdraw. 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 unto them: Spend of that wherewith Allah hath provided you, those who disbelieve say unto those who believe: Shall we feed those whom Allah, if He willed, would feed? Ye are in naught else than error manifest. 47 And they say: "When will this promise (i.e. Resurrection) be fulfilled, if you are truthful?" 48 They await only but a single Saihah (shout, etc.), which will seize them while they are disputing! 49 They will have no time to make a will, nor shall they return to their own people. 50
