MUSLIM 319b:
from ʿĀʾishah —
The Messenger of Allah ﷺ took a bath from the vessel (which contained seven to eight seers, i. e. fifteen to sixteen pounds) of water And I and he (the Holy Prophet) took a bath from the same vessel. And in the hadith narrated by Sufyan the words are:" from one vessel". Qutaiba said: Al-Faraq is three Sa' (a cubic measuring of varying magnitude).
مسلم ٣١٩b:
عن عاءشه —
كَانَ رَسُولُ اللَّهِ ﷺ يَغْتَسِلُ فِي الْقَدَحِ وَهُوَ الْفَرَقُ وَكُنْتُ أَغْتَسِلُ أَنَا وَهُوَ فِي الإِنَاءِ الْوَاحِدِ وَفِي حَدِيثِ سُفْيَانَ مِنْ إِنَاءٍ وَاحِدٍ قَالَ قُتَيْبَةُ قَالَ سُفْيَانُ وَالْفَرَقُ ثَلاَثَةُ آصُعٍ
