Yahya related to me from Malik from AbuRijal Muhammad ibn Abd ar-
Rahman from Amra bint Abd ar-Rahman that when A'isha umm al-muminin
was doing hajj with women who were expecting their periods, she would
hurry them to do the tawaf al-ifada on the Day of Sacrifice. If they
started to menstruate after the tawaf al-ifada she did not stop for
them but left with them while they were menstruating.
Muwatta Malik Book 20, Hadith 239
