And a sign for them is the dead earth. We have brought it to life and brought forth from it grain, and from it 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 That they may eat of the fruit thereof; and their hands worked it not. Will they not, therefore, give 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 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 And (as for) the moon, We have ordained for it stages till it becomes again as an old dry palm branch. 39 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 And We have created for them similar ships, in which they now ride. 42 And if We will, We drown them, and there is no help for them, neither can they be saved; 43 It is only by Our mercy that they are granted provision 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 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: expend of that wherewith Allah hath provided you, those who disbelieve say unto those who believe: shall we feed those whom God Himself would have fed, if He listed? Ye are in naught else than error manifest. 47 And they say: When will this promise be fulfilled, if ye 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 And they will not be able [to give] any instruction, nor to their people can they return. 50
