Abu Dawud Book 4, Hadith Number 2024.

Chapter : Not known.

Narated By ‘Aisha, Ummul Mu’minin : The Prophet (PBUH) went out from me, while he was happy, but he returned to me while he was sad. He said: I entered the Ka’bah, I know beforehand about my affair what I have come to know later I would not have entered it. I am afraid I have put my community to hardship.
