There is a sign for them in the lifeless earth. We revive it and We produce grain from it of which they eat. 33 And We placed therein gardens of palm trees and grapevines and caused to burst forth therefrom some springs - 34 that they might eat of its fruits. It was not their hands that made them. Will they not, then, 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 unto them is the night. We draw off the day therefrom, and lo! they are darkened. 37 And the sun -- it runs to a fixed resting-place; that is the ordaining of the All-mighty, the All-knowing. 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 39 The sun cannot overtake the moon, nor can the night outpace the day: each floats in [its own] orbit. 40 And a sign to 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 will, We shall drown them, and there will be no shout (or helper) for them (to hear their cry for help) nor will they be saved. 43 But (by) mercy from Us and for enjoyment till a time. 44 But when it is said to them, "Beware of what is before you and what is behind you; perhaps you will receive mercy... " 45 And not a sign cometh unto them of the signs of their Lord, but they are ever backsliders therefrom. 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 be fulfilled, if you are truthful?” 48 They will not (have to) wait for aught but a single Blast: it will seize them while they are yet disputing among themselves! 49 and they will not even be able to make a testament, nor to return to their households. 50
