And a sign for them is the dead land. We gave it life, and We brought forth from it grains, so that they eat thereof. 33 and [how] We make gardens of date-palms and vines [grow] thereon, and cause springs to gush [forth] within it, 34 so that they may eat of the fruit thereof, though it was not their hands that made it. Will they not, then, be grateful? 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 A sign for them is the night. From it We withdraw the day and they are in darkness. 37 And the sun runs on to a term appointed for it; that is the ordinance of the Mighty, the Knowing. 38 And the moon - We have determined for it phases, until it returns [appearing] like the old date stalk. 39 It is not allowable for the sun to reach the moon, nor does the night overtake the day, but each, in an orbit, is swimming. 40 And a sign unto them is that We bear their offspring in a laden ship. 41 And We have created for them the like of it in which they board. 42 Had We wanted, We could have drowned them and nothing would have been able to help or rescue them 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 They also say, 'When shall this promise come to pass, if you speak truly?' 48 They wait not for aught but a single cry which will overtake them while they yet contend with one another. 49 Then they would not be able to make a will, or go back to their people. 50
