Let the dead earth be a Sign for them. We gave it life and produced from it grain whereof they eat. 33 And We place therein gardens of the date-palms and vines; and We therein cause to gush forth springs. 34 So that they may eat of its fruit; yet it was not done by their hands. Then why do they not acknowledge thanks? 35 Exalted is He who created all pairs - from what the earth grows and from themselves and from that which 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 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 measured for it mansions (to traverse) till it returns like the old dried curved date stalk. 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 That We bore their progeny in the laden ark is a sign for them; 41 And We have created for them the like of it in which they board. 42 And if We will, We can drown them, so there would be no help in their distress, nor would 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 Never came a token of the tokens of their Lord to them, but they did turn 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 wait not for aught but a single cry which will overtake them while they yet contend with one another. 49 Therefore neither able to make a will, nor returning to their homes. 50
