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 ‏.‏

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-mumininwas doing hajj with women who were expecting their periods, she wouldhurry them to do the tawaf al-ifada on the Day of Sacrifice. If theystarted to menstruate after the tawaf al-ifada she did not stop forthem but left with them while they were menstruating. Translation Not Available
