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 place therein gardens of the date-palms and vines; and We therein cause to gush forth springs. 34 so that they might eat of its fruit and the labor of their hands. Will they not give thanks? 35 Purity is to Him Who created all pairs, from what the earth grows, and of themselves, and from the things 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 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 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 And [it ought to be] a sign for them that We bear their offspring [over the seas] in laden ships, 41 And We created for them from the likes of it that which they ride. 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 unto them: Beware of that which is before you and that which is behind you, that haply ye may find mercy (they are heedless). 45 Yet there never comes to them any sign of their Lord's signs, but they turn away from it. 46 When they are told: "Spend of what God has given you," the unbelievers say to those who believe: "Why should we feed those whom God should have fed if He pleased?" You are only in palpable error. 47 They say: “When will this threat (of Resurrection) come to pass? Tell us if indeed you are truthful.” 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
