Sahih Muslim 890c
Umm 'Atiyya reported: The Messenger of Allah ﷺ commanded us to bring out on'Id-ul-Fitr and 'Id-ul-Adha young women, menstruating women and purdah-observing ladies, menstruating women kept back from prayer, but participated in goodness and supplication of the Muslims. I said: Messenger of Allah, one of us does not have an outer garment (to cover her face and body). He said: Let her sister cover her with her outer garment.
وَحَدَّثَنَا عَمْرٌو النَّاقِدُ، حَدَّثَنَا عِيسَى بْنُ يُونُسَ، حَدَّثَنَا هِشَامٌ، عَنْ حَفْصَةَ بِنْتِ، سِيرِينَ عَنْ أُمِّ عَطِيَّةَ، قَالَتْ أَمَرَنَا رَسُولُ اللَّهِ ﷺ أَنْ نُخْرِجَهُنَّ فِي الْفِطْرِ وَالأَضْحَى الْعَوَاتِقَ وَالْحُيَّضَ وَذَوَاتِ الْخُدُورِ فَأَمَّا الْحُيَّضُ فَيَعْتَزِلْنَ الصَّلاَةَ وَيَشْهَدْنَ الْخَيْرَ وَدَعْوَةَ الْمُسْلِمِينَ . قُلْتُ يَا رَسُولَ اللَّهِ إِحْدَانَا لاَ يَكُونُ لَهَا جِلْبَابٌ قَالَ " لِتُلْبِسْهَا أُخْتُهَا مِنْ جِلْبَابِهَا " .
