The Rites of Hajj (Kitab Al-Manasik Wa'l-Hajj)
Dawud :: Book 10 : Hadith 2024
Narrated Aisha, Ummul Mu'minin:
The Prophet (peace_be_upon_him) 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.
