Al-Matalib al-'Aliyah 4 — The amount of water sufficient for wudu

Yazid al-Raqashi narrates from a woman of his people that she said: I visited the Mother of the Believers, Sayyidah Umm Salamah (may Allah be pleased with her), and said, Show me (the vessels used by the Prophet (peace and blessings be upon him)). Then the narrator mentioned the whole hadith, in which it is mentioned that Sayyidah Umm Salamah (may Allah be pleased with her) said about the vessel for the ritual bath: "This is a makhtum," meaning a vessel with the capacity of one sa'; and she said about the vessel for ablution: "This is a quarter of the mufti (a measure of that name)," meaning that its capacity is equal to one mudd. There is some weakness in the chain of this hadith.
