حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا أَبُو خَيْثَمَةَ، عَنْ عَاصِمٍ الأَحْوَلِ، عَنْ حَفْصَةَ بِنْتِ، سِيرِينَ عَنْ أُمِّ عَطِيَّةَ، قَالَتْ كُنَّا نُؤْمَرُ بِالْخُرُوجِ فِي الْعِيدَيْنِ وَالْمُخَبَّأَةُ وَالْبِكْرُ قَالَتِ الْحُيَّضُ يَخْرُجْنَ فَيَكُنَّ خَلْفَ النَّاسِ يُكَبِّرْنَ مَعَ النَّاسِ .
