There is a sign for them in the lifeless earth. We revive it and We produce grain from it of which they eat. 33 We have laid out gardens of dates and grapes upon it, and made springs of water flow, 34 so that they may eat of the fruit thereof, though it was not their hands that made it. Will they not, then, be grateful? 35 Holy is He who created all things in pairs; of what the earth grows, and of themselves, and other things which they do not know. 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 runs his course for a period determined for him: that is the decree of (Him), the Exalted in Might, the All-Knowing. 38 And We have appointed positions for the moon till it returns like an old branch of the date palm. 39 It is not permitted to the sun that it should overtake the moon, nor can the night outstrip the day: each in an orbit, they float. 40 Another sign for them is that We carried their offspring in the laden Ark. 41 And We have created for them the like of it, what they will ride on. 42 We drown them if We will, then they have none to cry to, nor 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 And when it is said to them, 'Fear what is before you and what is behind you; haply you will find mercy' -- 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 of that with which Allah has provided you," those who disbelieve say to those who believe: "Shall we feed those whom, if Allah willed, He (Himself) would have fed? You are only in a plain error." 47 And they say: When will this threat come to pass, if you are truthful? 48 They will not have to wait long. When the Day of Judgment comes, it will only take a single blast of sound to strike them while they are quarrelling with one another. 49 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
