And a sign to them is the dead earth: We give life to it and bring forth from it grain so they eat of it. 33 And We produce therein orchard with date-palms and vines, and We cause springs 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 Glory be to Him, who created all the pairs of what the earth produces, and of themselves, and of what they know not. 36 And a sign for them is the night; We strip it of the day and lo, they are in darkness. 37 While the sun keeps revolving in its orbit. This is the dispensation of the mighty, all-knowing (God). 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 39 [and] neither may the sun overtake the moon, nor can the night usurp the time of day, since all of them float through space [in accordance with Our laws]. 40 And a sign for them is that We carried their forefathers in a laden ship. 41 And We have created for them similar ships, in which they now ride. 42 If it were Our Will, We could drown them: then would there be no helper (to hear their cry), nor could they be delivered, 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 Never does any Sign of their Lord come to them, 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 They say, "When will this promise be fulfilled, if you are truthful?" 48 The Truth is that they are waiting for nothing but a mighty Blast to seize them the while they are disputing (in their worldly affairs), 49 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
