البخاري:٢٧٧حَدَّثَنَا خَلاَّدُ بْنُ يَحْيَى قَالَ حَدَّثَنَا إِبْرَاهِيمُ بْنُ نَافِعٍ عَنِ الْحَسَنِ بْنِ مُسْلِمٍ عَنْ صَفِيَّةَ بِنْتِ شَيْبَةَ عَنْ عَائِشَةَ قَالَتْ

كُنَّا إِذَا أَصَابَتْ إِحْدَانَا جَنَابَةٌ أَخَذَتْ بِيَدَيْهَا ثَلاَثًا فَوْقَ رَأْسِهَا ثُمَّ تَأْخُذُ بِيَدِهَا عَلَى شِقِّهَا الأَيْمَنِ وَبِيَدِهَا الأُخْرَى عَلَى شِقِّهَا الأَيْسَرِ
