كتاب صلاة الجماعة

Prayer in Congregation

Yahya related to me from Malik that he had heard that A'isha, the wife of the Prophet, may Allah bless him and grant him peace, used to pray in a shift and head-covering.

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَائِشَةَ، زَوْجَ النَّبِيِّ صلى الله عليه وسلم كَانَتْ تُصَلِّي فِي الدِّرْعِ وَالْخِمَارِ ‏.‏
