Sahih Muslim Book 040, Hadith Number 6782.

Chapter : Not known.

Abu Huraira reported Allah's Messenger (may peace be upon him) said that Allah, the Exalted and Glorious, said: I have prepared for My pious servants which the eye has seen not, and the ear has heard not and no human heart has ever perceived such bounties leaving aside those about which Allah has informed you. He then recited: "No soul knows what comfort has been hidden for them".
