There is a sign in the dead earth for them which We quicken, and produce from it grain 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 from its fruits, whereas they are not manufactured by their hands! So will they not be grateful? 35 Holy is He Who created all things in pairs, whether it be of what the earth produces, and of themselves, and of what 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 on its fixed course for a term (appointed). That is the Decree of the All-Mighty, the All-Knowing. 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 39 It is not for the sun to catch up with the moon, nor does the night surpass the day; and each one of them floats in its orbit. 40 That We bore their progeny in the laden ark is a sign for them; 41 And We have created for them of the like thereunto, so on them they ride. 42 And if We list, We shall drown them, and there will be no shout for them, nor will they be saved. 43 But (by) mercy from Us and for enjoyment till a time. 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 yet never any sign of the signs of their Lord comes to them, but they are turning away from it. 46 And when it is said to them, "Spend from that which Allah has provided for you," those who disbelieve say to those who believe, "Should we feed one whom, if Allah had willed, He would have fed? You are not but in clear error." 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 will not be able to make any testament, nor will they return to their people. 50
