Sahih Muslim Book - 8, Hadith - 2056

وَحَدَّثَنَا عَمْرٌو النَّاقِدُ حَدَّثَنَا عِيسَى بْنُ يُونُسَ حَدَّثَنَا هِشَامٌ عَنْ حَفْصَةَ بِنْتِ سِيرِينَ عَنْ أُمِّ عَطِيَّةَ قَالَتْ أَمَرَنَا رَسُولُ اللَّهِ -صلى الله عليه وسلم- أَنْ نُخْرِجَهُنَّ فِى 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 ».

It was narrated that Umm 'Atiyyah said: "On Al-Fitr and Al-Adha, the Messenger of Allah (s.a.w) commanded us to bring out the girls who had reached puberty, menstruating women and women in seclusion. The menstruating women were to keep away from the prayer but to witness goodness and the supplications of the Muslims. I said: 'O Messenger of Allah, one of us may not have a Jilbab.' He said: 'Let her sister lend her a Jilbab to wear."'
