Musannaf Ibn Abi Shaybah 713 — How much water suffices a person

Sayyiduna Jabir (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) said: "One mudd of water suffices for ablution (wudu), and one sa' for the ritual bath (ghusl)." A man asked: "O Jabir! How much is enough for us?" He said: "As much as was enough for one who was better than you and had more hair than you, that is, the Prophet (peace and blessings be upon him)."
