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.

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 .
