The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 33 We have placed in it gardens of date palms and vines, and caused springs to gush [forth] from it, 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 a sign unto them is the night. We draw off the day therefrom, and lo! they are darkened. 37 And the sun runs its course for its final destination; this is a command of the Almighty, the All Knowing. 38 We have determined the stations of the moon, so that (after its wanderings) it returns as a dried up inflorescent spike of dates. 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 for them is that We carried their offspring in the laden Ark (of Noah). 41 And have created for them of the like thereof 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 It is only Our Mercy (that rescues them) and enables enjoyment of life for a while. 44 And [yet,] when they are told, "Beware of [God's insight into] all that lies open before you and all that is hidden from you, so that you might be graced with His mercy," [most men choose to remain deaf;] 45 Never does any Sign of their Lord come to them, but they turn away from it. 46 Thus, when they are told, "Spend on others out of what God has provided for you as sustenance," those who are bent on denying the truth say unto those who believe, "Shall we feed anyone whom, if [your] God had so willed, He could have fed [Himself]? Clearly, you are but lost in error!" 47 Further, they say, "When will this promise (come to pass), if what ye say is true?" 48 They must be waiting for but one single blast, which will overtake them while they are still disputing. 49 then they will not be able to make any testament, nor will they return to their people. 50
