The dead land is a sign for them. We revive it, and from it produce grain from which they eat. 33 And We make therein gardens of palms and grapevines and We make springs to flow forth in it, 34 that they might eat of its fruits and their hands' labour. What, will they not be thankful? 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 [of Our sway over all that exists] they have a sign in the night: We withdraw from it the [light of] day - and lo! they are in darkness. 37 And the sun runneth on unto a resting-place for him. That is the measuring of the Mighty, the Wise. 38 And the Moon,- We have measured for her mansions (to traverse) till she returns like the old (and withered) lower part of a date-stalk. 39 The sun cannot overtake the moon, nor can the night outpace the day: each floats in [its own] orbit. 40 how We carried them and their offspring inside the laden Ark 41 And We have created for them the like of it in which they board. 42 We could have drowned them if We pleased, and none would have answered their cry for help, nor would they have been saved, 43 Unless by mercy from Us, and as a comfort for a while. 44 When they are told, "guard yourselves against what is before you and what is behind you, in order that you may be shown mercy," [they turn away]. 45 and whenever a revelation out of their Lord's revelations comes to them, they ignore 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 are only waiting for a single blast that will seize them, but they will go on contending. 49 then they will not be able to make any testament, nor will they return to their people. 50
