And a sign for them is the dead land. We gave it life, and We brought forth from it grains, so that they eat thereof. 33 And We make therein gardens of palms and grapevines and We make springs to flow forth in it, 34 that they might eat of its fruits. It was not their hands that made them. Will they not, then, give thanks? 35 Glory to Allah, Who created in pairs all things that the earth produces, as well as their own (human) kind and (other) things of which they have no knowledge. 36 And a sign for them is the night; We strip the day out of it, thereupon they are in darkness. 37 And the sun runneth on unto a resting-place for him. That is the measuring of the Mighty, the Wise. 38 And the moon -- We have determined it by stations, till it returns like an aged palm-bough. 39 It is not for the sun to catch up with the moon, nor does the night surpass the day; and each one of them floats in its 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 And if We will, We drown them, and there is no help for them, neither can they be saved; 43 unless it be by an act of mercy from Us and a grant of life for a [further span of] 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 None of the signs of their Lord ever comes to them but they turn away from it. 46 And when it is said to them, “Spend in Allah’s cause, from what Allah has provided you”, the disbelievers say regarding the believers, “Shall we feed these, whom if Allah willed, would have fed? You are not but in open error!” 47 They say: “When will this threat (of Resurrection) come to pass? Tell us if indeed you are truthful.” 48 They wait not for aught but a single cry which will overtake them while they yet contend with one another. 49 then they will not be able to make any testament, nor will they return to their people. 50
