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 placed therein gardens of palm trees and grapevines and caused to burst forth therefrom some springs - 34 so that they may eat its fruit, though it was not their hands that made this. 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 And a sign for them is the 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 by stations, till it returns like an aged palm-bough. 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 And a sign for them is that We lodged them in a laden ship, while they were in their forefathers backs. 41 and then created for them other vessels like those on which they ride. 42 And if We list, We shall drown them, and there will be no shout for them, nor will they be saved. 43 except Our mercy which could enable them to enjoy themselves for an appointed time. 44 And when it is said to them, 'Fear what is before you and what is behind you; haply you will find mercy' -- 45 And there comes not to them a communication of the communications of their Lord but they turn aside from it. 46 Thus, when they are told, "Spend on others out of what God has provided for you as sustenance," those who are bent on denying the truth say unto those who believe, "Shall we feed anyone whom, if [your] God had so willed, He could have fed [Himself]? Clearly, you are but lost in error!" 47 And they say, “When will this promise be fulfilled, if 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 cannot make bequest, nor can they return to their own folk. 50
