And a sign to them is the dead earth: We give life to it and bring forth from it grain so they eat of it. 33 And We produce therein orchard with date-palms and vines, and We cause springs to gush forth therein: 34 That they may enjoy the fruits of this (artistry): It was not their hands that made this: will they not then give thanks? 35 Purity is to Him Who created all pairs, from what the earth grows, and of themselves, and from the things they do not know. 36 And a sign for them is the night, We withdraw therefrom the day, and behold, 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 We have ordained phases for the moon until finally it becomes like an old date-stalk. 39 Neither can the sun overtake the moon, nor the night outpace the day: Each of them keeps coursing in its orbit. 40 And a sign for them is that We carried their seed in the laden ship, 41 And We have created for them similar ships, in which they now ride. 42 And if We will, We drown them, and there is no help for them, neither can they be saved; 43 It is only by Our mercy that they are granted provision for a 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 yet never any sign of the signs of their Lord comes to them, but they are turning away from it. 46 And when it is said to them, 'Expend of that God has provided you,' the unbelievers say to the believers, 'What, shall we feed such a one whom, if God willed, He would feed? You are only in manifest error!' 47 They also say, 'When shall this promise come to pass, if you speak truly?' 48 They await only but a single Saihah (shout, etc.), which will seize them while they are disputing! 49 And they will not be able to make a disposition, nor to their family they return. 50
