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 its fruit, though it was not their hands that made this. Will they not then be grateful? 35 Glory be to Him, Who has created all the pairs of that which the earth produces, as well as of their own (human) kind (male and female), and of that which they know not. 36 And a Sign for them is the Night: We withdraw therefrom the Day, and behold they are plunged in darkness; 37 And the sun runs [on course] toward its stopping point. That is the determination of the Exalted in Might, the Knowing. 38 And for the moon We have appointed mansions till she return like an old shrivelled palm-leaf. 39 Neither is it allowable to the sun that it should overtake the moon, nor can the night outstrip the day; and all float on in a sphere. 40 Another Sign for them is that We carried all their offspring in the laden vessel 41 and created for them similar things to ride. 42 We drown them if We will, then they have none to cry to, nor can they be saved, 43 Unless by mercy from Us, and as a comfort for a while. 44 When they are told, "Fear ye that which is before you and that which will be after you, in order that ye may receive Mercy," (they turn back). 45 and no message of their Sustainer's messages ever reaches them without their turning away from it. 46 And when they are told, "Spend ye of (the bounties) with which Allah has provided you," the Unbelievers say to those who believe: "Shall we then feed those whom, if Allah had so willed, He would have fed, (Himself)? Ye are in nothing but manifest error." 47 They also say, 'When shall this promise come to pass, if you speak truly?' 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 Therefore neither able to make a will, nor returning to their homes. 50
