Beginning of Creation
Bukhari :: Book 4 :: Volume 54 :: Hadith 475
Narrated Abu Huraira:
The Prophet said "There is a tree in Paradise (which is so big and huge that) a rider could travel in its shade for a hundred years. And if you wish, you can recite:--'In shade long extended..' (56. 30) and a place in Paradise equal to an arrow bow of one of you, is better than (the whole earth) on which the sun rises and sets."
