And a sign for them is the dead land, that We quickened and brought forth from it grain, whereof they eat; 33 and produced therein grains from which they eat and established therein gardens of palms trees and vineyards and have made streams flow therein 34 That they may eat of the fruit thereof; and their hands worked it not. Will they not, therefore, give thanks? 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 how We ordained the moon to pass through certain phases until it seems eventually to be like a bent twig; 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 bore their race (through the Flood) in the loaded Ark; 41 and then created for them other vessels like those on 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 except through Our Mercy and as enjoyment for awhile. 44 But when it is said to them, "Beware of what is before you and what is behind you; perhaps you will receive mercy... " 45 Yet there never comes to them any sign of their Lord's signs, but they turn away from it. 46 And when it is said to them: "Spend of that with which Allah has provided you," those who disbelieve say to those who believe: "Shall we feed those whom, if Allah willed, He (Himself) would have fed? You are only in a 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 await just one scream, which will overcome them while they are involved in worldly disputes. 49 And they will not be able [to give] any instruction, nor to their people can they return. 50
