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 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 Hallowed be He who hath created all the pairs of that which the earth groweth, and of themselves and of that which they know not! 36 They have a sign in the night: We withdraw from it the [light of] day -- and they are left in darkness. 37 The sun is running its course to its appointed place. That is the ordaining of the All-Mighty, the All-Knowing. 38 And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. 39 The sun cannot overtake the moon, nor can the night outpace the day: each floats in [its own] orbit. 40 And a sign for them is that We carried their offspring in the laden Ark (of Noah). 41 And We have created for them the like of it, what they will ride on. 42 And if We will, We can drown them, so there would be no help in their distress, nor would they be saved. 43 Except by way of Mercy from Us, and by way of (world) convenience (to serve them) for 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: 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 add, "When is this promise [of resurrection] to be fulfilled? [Answer this] if you are men of truth!" 48 They do not await except one blast which will seize them while they are disputing. 49 They will have no time to make a will, nor shall they return to their own people. 50
