And a sign for them is the dead earth. We have brought it to life and brought forth from it grain, and from it they eat. 33 We made in it gardens of date-palms and vines, and We caused springs to gush forth 34 That they may eat of the fruit thereof, and their hands did not make it; will they not then be grateful? 35 Glory be to Him, who created all the pairs of what the earth produces, and of themselves, and of what they know not. 36 A token unto them is night. We strip it of the day, and lo! they are in darkness. 37 The sun is running its course to its appointed place. That is the ordaining of the All-Mighty, the All-Knowing. 38 And the moon, We have determined it in phases till it returns like an old palmbranch. 39 Neither is it allowable to the sun that it should overtake the moon, nor can the night outstrip the day; and all float on in a sphere. 40 Another Sign for them is that We carried all their offspring in the laden vessel 41 And We made similar vessels for them to ride. 42 If it were Our Will, We could drown them: then would there be no helper (to hear their cry), nor could they be delivered, 43 It is only Our Mercy (that rescues them) and enables enjoyment of life for a while. 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 to spend for the cause of God out of what He has provided for them for their sustenance, the disbelievers say to the believers, "Should we feed those whom God has decided to feed? You are in plain error." 47 And they add, "When is this promise [of resurrection] to be fulfilled? [Answer this] if you are men of truth!" 48 They wait not for aught but a single cry which will overtake them while they yet contend with one another. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
