Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him) narrated: We mentioned the ritual bath (ghusl) for major impurity (janabah) in the presence of the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said: "As for me, I perform ablution (wudu) as for the prayer, then I take a palmful of water three times and pour it over my head, then I bathe."
