Muwatta Imam Malik Book of Hajj, Hadith 236

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.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ أَبِي الرِّجَالِ، مُحَمَّدِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ عَمْرَةَ بِنْتِ عَبْدِ الرَّحْمَنِ، . أَنَّ عَائِشَةَ أُمَّ الْمُؤْمِنِينَ، كَانَتْ إِذَا حَجَّتْ وَمَعَهَا نِسَاءٌ تَخَافُ أَنْ يَحِضْنَ قَدَّمَتْهُنَّ يَوْمَ النَّحْرِ فَأَفَضْنَ فَإِنْ حِضْنَ بَعْدَ ذَلِكَ لَمْ تَنْتَظِرْهُنَّ فَتَنْفِرُ بِهِنَّ - وَهُنَّ حُيَّضٌ - إِذَا كُنَّ قَدْ أَفَضْنَ .
