And a sign for them is the dead earth; We gave it life and We produced from it grain, so they eat from it. 33 and We made therein gardens of palms and vines, and therein We caused fountains to gush forth, 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 Exalted is He who created all pairs - from what the earth grows and from themselves and from that which they do not know. 36 And a sign unto them is the night. We draw off the day therefrom, and lo! they are darkened. 37 And [they have a sign in] the sun: it runs in an orbit of its own [and] that is laid down by the will 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 It behoves not the sun to overtake the moon, neither does the night outstrip the day, each swimming in a sky. 40 And a sign for them is that We carried their seed in the laden ship, 41 and [that] We create for them things of a similar kind, on which they may embark [in their travels]; 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 it be by an act of mercy from Us and a grant of life for a [further span of] 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 and no message of their Sustainer's messages ever reaches them without their turning away from it. 46 and when they are told, "Give to others out of what God has provided for you," those who are bent on denying the truth say to the believers, "Why should we feed those whom God could feed if He wanted? You are clearly in error!" 47 And they say: When will this threat come to pass, if you are truthful? 48 They are awaiting only for one Cry to seize them while they are yet disputing, 49 Then they will not be able to make a will or return to their families. 50
