Muwatta Imam Malik Book of Purity, Hadith 70
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 ﷺ used to do ghusl for major ritual impurity from a vessel which contained a faraq.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ، أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَغْتَسِلُ مِنْ إِنَاءٍ - هُوَ الْفَرَقُ - مِنَ الْجَنَابَةِ .
