A token unto them is the dead earth. We revive it, and We bring forth from it grain so that they eat thereof; 33 We have laid out gardens of dates and grapes upon it, and made springs of water flow, 34 so that they might eat of its fruit and the labor of their hands. Will they not 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 And the night is another Sign for them. We strip the day from it and they become plunged in darkness. 37 The sun, too, follows its determined course laid down for it by the Almighty, the All Knowing. 38 and [in] the moon, for which We have determined phases [which it must traverse] till it becomes like an old date-stalk, dried-up and curved: 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 And a sign unto them is that We bear their offspring in a laden ship. 41 And We have created for them of the like thereunto whereon they ride. 42 and [that,] if such be Our will, We may cause them to drown, with none to respond to their cry for help: and [then] they cannot be saved, 43 Unless by mercy from Us and as comfort for a while. 44 And when it is said to them: Guard against what is before you and what is behind you, that mercy may be had on you. 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 to them: "Spend of that with which Allah has provided you," those who disbelieve say to those who believe: "Shall we feed those whom, if Allah willed, He (Himself) would have fed? You are only in a plain error." 47 And they say: When will this promise be fulfilled, if ye are truthful? 48 They must be waiting for but one single blast, which will overtake them while they are still disputing. 49 and so [sudden will be their end that] no testament will they be able to make, - nor to their own people will they return! 50
