It was narrated from 'Aishah that the Messenger of Allah ﷺ used to perform Ghusl, he and I from a single vessel, both of us scooping water from it.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَغْتَسِلُ وَأَنَا مِنْ إِنَاءٍ وَاحِدٍ نَغْتَرِفُ مِنْهُ جَمِيعًا وَقَالَ سُوَيْدٌ قَالَتْ كُنْتُ أَنَا  

"I heard Al-Qasim narrating that 'Aishah said: 'I used to perform Ghusl - the Messenger of Allah ﷺ and I - from a single vessel for Janabah.'"  

كُنْتُ أَغْتَسِلُ أَنَا وَرَسُولُ اللَّهِ ﷺ مِنْ إِنَاءٍ وَاحِدٍ مِنَ الْجَنَابَةِ  

"I remember competing over the vessel [1] with the Messenger of Allah ﷺ, when he and I were performing Ghusl from it." [1] See the following narration and no. 240.  

لَقَدْ رَأَيْتُنِي أُنَازِعُ رَسُولَ اللَّهِ ﷺ الإِنَاءَ أَغْتَسِلُ أَنَا وَهُوَ مِنْهُ
