Hadith 1138
حَدَّثَنَا النُّفَيْلِيُّ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا عَاصِمٌ الأَحْوَلُ، عَنْ حَفْصَةَ بِنْتِ سِيرِينَ، عَنْ أُمِّ عَطِيَّةَ، قَالَتْ كُنَّا نُؤْمَرُ بِهَذَا الْخَبَرِ قَالَتْ وَالْحُيَّضُ يَكُنَّ خَلْفَ النَّاسِ فَيُكَبِّرْنَ مَعَ النَّاسِ .
This tradition has also been narrated by Umm 'Atiyyah though a different chain of transmitters. She said:
We were commanded to go out (for offering the 'Id prayer). She further said: The menstruating women stood behind the people and they uttered the takbir (Allah is most great) along with the people.
