أَخْبَرَنَا الْقَاسِمُ بْنُ زَكَرِيَّا بْنِ دِينَارٍ، قَالَ حَدَّثَنِي إِسْحَاقُ بْنُ مَنْصُورٍ، عَنْ إِبْرَاهِيمَ بْنِ سَعْدٍ، عَنِ الزُّهْرِيِّ، عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَغْتَسِلُ فِي الإِنَاءِ وَهُوَ الْفَرَقُ وَكُنْتُ أَغْتَسِلُ أَنَا وَهُوَ مِنْ إِنَاءٍ وَاحِدٍ .
