Hazrat Ja'far, may Allah have mercy on him, narrates from his father that he said: Sayyiduna Jabir bin Abdullah, may Allah be pleased with them both, said to me that your cousin Hasan bin Muhammad asked about the ritual bath (ghusl) after sexual impurity. So I said that the Messenger of Allah, peace and blessings be upon him, used to pour three handfuls (of water) over his head. He (Hasan) said: My hair is very thick. I said: The hair of the Messenger of Allah, peace and blessings be upon him, was more and more beautiful than yours. This is the hadith of Yahya bin Sa'id.
