The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 33 And there We made gardens of palms and vines, and in it We caused fountains to gush forth, 34 That they may eat of the fruit thereof; and their hands worked it not. Will they not, therefore, give thanks? 35 Purity is to Him Who created all pairs, from what the earth grows, and of themselves, and from the things they do not know. 36 They have a sign in the night: We withdraw from it the [light of] day -- and they are left 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 [and] neither may the sun overtake the moon, nor can the night usurp the time of day, since all of them float through space [in accordance with Our laws]. 40 That We bore their progeny in the laden ark is a sign for them; 41 And We made similar vessels for them to ride. 42 Should We so wish, We can drown them, and there will be none to heed their cries of distress, nor will they be rescued. 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 no sign comes to them from the signs of their Lord except that they are from it turning away. 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 They also say, 'When shall this promise come to pass, if you speak truly?' 48 They await only but a single Saihah (shout, etc.), which will seize them while they are disputing! 49 and they will not even be able to make a testament, nor to return to their households. 50
