Hadith 501000
Chapter 2: Purity - كتاب الطهارة
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَغْتَسِلُ مِنْ إِنَاءٍ - هُوَ الْفَرَقُ - مِنَ الْجَنَابَةِ .
Yahya related to me from Malik from Ibn Shihab from Urwa ibn az- Zubayr from A'isha, umm al-muminin, that the Messenger of Allah, may Allah bless him and grant him peace, used to do ghusl for major ritual impurity from a vessel which contained a faraq.
