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 placed therein gardens of palm trees and grapevines and caused to burst forth therefrom some springs - 34 So that they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 Limitless in His glory is He who has created opposites in whatever the earth produces, and in men's own selves, and in that of which [as yet] they have no knowledge. 36 And [of Our sway over all that exists] they have a sign in the night: We withdraw from it the [light of] day - and lo! they are in darkness. 37 And the sun runneth on unto a resting-place for him. That is the measuring of the Mighty, the Wise. 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 39 Neither does it lie in the sun's power to overtake the moon nor can the night outstrip the day. All glide along, each in its own orbit. 40 And [it ought to be] a sign for them that We bear their offspring [over the seas] in laden ships, 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 there would be no helper [to hear their cry], nor could they be saved. 43 But (by) mercy from Us and for enjoyment till a time. 44 Whenever they are told to guard themselves against sin and the forth coming torment so that perhaps they could receive mercy 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 And they say: When will this promise be fulfilled, if ye are truthful? 48 They are only waiting for a single blast that will seize them, but they will go on contending. 49 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
