And a sign to them is the dead earth: We give life to it and bring forth from it grain so they eat of it. 33 And We produce therein orchard with date-palms and vines, and We cause springs to gush forth therein: 34 that they might eat of its fruits and their hands' labour. What, will they not be thankful? 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 for them is the night, We withdraw therefrom the day, and behold, they are in darkness. 37 While the sun keeps revolving in its orbit. This is the dispensation of the mighty, all-knowing (God). 38 We have appointed stages for the moon till it returns in the shape of a dry old branch of palm-tree. 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 We have created for them the like of it in which they ride. 42 And if We will, We drown them, and there is no help for them, neither can they be saved; 43 Except by way of Mercy from Us, and by way of (world) convenience (to serve them) for a time. 44 But when it is said to them, "Beware of what is before you and what is behind you; perhaps you will receive mercy... " 45 Never came a token of the tokens of their Lord to them, but they did turn away from it! 46 And when it is said to them, 'Expend of that God has provided you,' the unbelievers say to the believers, 'What, shall we feed such a one whom, if God willed, He would feed? You are only in manifest error!' 47 The unbelievers say, "When will the Day of Judgment come if what you say is at all true?" 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
