Yahya related to me from Malik from Nafi that Abdullah ibn Umardivorced one of his wives in the house of Hafsa, the wife of theProphet, may Allah bless him and grant him peace, while he was on theway to the mosque. He went another route from behind the houses beingaverse to ask permission to enter until he returned to her.
