And a sign for them is the dead earth; We gave it life and We produced from it grain, so they eat from it. 33 and We made therein gardens of palms and vines, and therein We caused fountains to gush forth, 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 a sign to them is the night: We draw forth from it the day, then lo! they are in the dark; 37 The sun, too, follows its determined course laid down for it by the Almighty, the All Knowing. 38 And the moon -- We have determined it by stations, till it returns like an aged palm-bough. 39 The sun shall not outstrip the moon, nor shall the night outstrip the day. Each is floating in an orbit. 40 And a sign for them is that We lodged them in a laden ship, while they were in their forefathers backs. 41 And We made similar vessels for them to ride. 42 Had We wanted, We could have drowned them and nothing would have been able to help or rescue them 43 unless it be by an act of mercy from Us and a grant of life for a [further span of] time. 44 And when it is said to them, “Beware of what is before you and what is behind you, in the hope of your gaining mercy”, they turn away! 45 And no sign comes to them from the signs of their Lord except that they are from it turning away. 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 say, "When will this promise be fulfilled, if you are truthful?" 48 They await but one Shout, which will surprise them while they are disputing. 49 No (chance) will they then have, by will, to dispose (of their affairs), nor to return to their own people! 50
