There is a sign for them in the lifeless earth. We revive it and We produce grain from it of which they eat. 33 and [how] We make gardens of date-palms and vines [grow] thereon, and cause springs to gush [forth] within it, 34 So that they may eat of the fruit thereof, and their hands made it not. Will they not, then, give thanks? 35 Glory be to Him Who created pairs of all things, of what the earth grows, and of their kind 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 [in] the moon, for which We have determined phases [which it must traverse] till it becomes like an old date-stalk, dried-up and curved: 39 Neither does it lie in the sun's power to overtake the moon nor can the night outstrip the day. All glide along, each in its own orbit. 40 And [it ought to be] a sign for them that We bear their offspring [over the seas] in laden ships, 41 and created for them similar things to ride. 42 And if We list, We shall drown them, and there will be no shout for them, nor will they be saved. 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 And not a sign cometh unto them of the signs of their Lord, but they are ever backsliders therefrom. 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 say: "When will this promise (i.e. Resurrection) be fulfilled, if you are truthful?" 48 They await not but one shout, which shall lay hold of them while they are yet wrangling. 49 They will have no time to make a will, nor shall they return to their own people. 50
