Yahya related to me from Malik from Abdullah ibn Abi Bakr ibn
Hazm from his father from Amra bint Abd ar-Rahman that A'isha umm al-
muminin said to the Messenger of Allah, may Allah bless him and grant
him peace, "Messenger of Allah, Safiyya bint Huyy has begun her
period," and the Messenger of Allah, may Allah bless him and grant him
peace, said, "Perhaps she will delay us. Has she done tawaf of the
House with you?" They said, "Of course." He said, "So you are free to
leave."
Muwatta Malik Book 20, Hadith 238
