Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 And We have placed in it gardens of dates and grapes, and We have made springs of water in it. 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, whether it be of what the earth produces, and of themselves, and of what they do not know. 36 A sign for them is the night. From it We withdraw the day and 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 the moon -- We have determined it by stations, till it returns like an aged palm-bough. 39 Neither does it lie in the sun's power to overtake the moon nor can the night outstrip the day. All glide along, each in its own orbit. 40 And a Sign for them is that We bore their race (through the Flood) in the loaded Ark; 41 And We have created for them the like of it, what they will ride on. 42 And if We will, We shall drown them, and there will be no shout (or helper) for them (to hear their cry for help) nor will they be saved. 43 It is only by Our mercy that they are granted provision for a time. 44 When it is said to them: "Beware of what is before you and what is past, that you may be treated with kindness;" 45 Yet there never comes to them any sign of their Lord's signs, but they turn away from it. 46 And when it is said to them: Spend out of what Allah has given you, those who disbelieve say to those who believe: Shall we feed him whom, if Allah please, He could feed? You are in naught but clear error. 47 And they say: "When will this promise come to pass, if what you say is 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
