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 make therein gardens of palms and grapevines and We make springs to flow forth in it, 34 So that they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 All glory to Him who created pairs of everything that grows from the earth, and out of themselves, and other things they do not know. 36 And the night is another Sign for them. We strip the day from it and they become plunged in darkness. 37 And the sun runs its course for its final destination; this is a command of the Almighty, the All Knowing. 38 And the Moon,- We have measured for her mansions (to traverse) till she returns like the old (and withered) lower part of a date-stalk. 39 Neither is it allowable to the sun that it should overtake the moon, nor can the night outstrip the day; and all float on in a sphere. 40 That We bore their progeny in the laden ark is a sign for them; 41 And We have created for them similar (vessels) on which they 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 Except by way of Mercy from Us, and by way of (world) convenience (to serve them) for a time. 44 And when it is said to them, “Beware of what is before you and what is behind you, in the hope of your gaining mercy”, they turn away! 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 to them: Spend out of what Allah has given you, those who disbelieve say to those who believe: Shall we feed him whom, if Allah please, He could feed? You are in naught but clear error. 47 And they say: when will this promise be fulfilled if ye say sooth? 48 They await but one Shout, which will seize them while they dispute. 49 then they will not be able to make any testament, nor will they return to their people. 50
