مُوَطَّأُ مَالِكٍ
Muwatta Malik 328
Prayer in Congregation
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، أَنَّ امْرَأَةً، اسْتَفْتَتْهُ فَقَالَتْ إِنَّ الْمِنْطَقَ يَشُقُّ عَلَىَّ أَفَأُصَلِّي فِي دِرْعٍ وَخِمَارٍ فَقَالَ نَعَمْ إِذَا كَانَ الدِّرْعُ سَابِغًا .
Yahya related to me from Malik from Hisham ibn Urwa from his father that a woman asked him for a decision, saying, "Waist-wrappers are painful to me. Can I pray in a shift and head-covering?" He replied, "Yes, if the shift is long."
