Sayyiduna Sahl bin Sa’d Sa’idi (may Allah be pleased with him), who saw and heard the Noble Prophet (peace and blessings be upon him), and at the time of the Prophet’s passing Sahl was 15 years old, narrated that Sayyiduna Ubayy bin Ka’b (may Allah be pleased with him) told me that the verdict“water (semen) for water (obligatory bath)”which people used to give, was a concession that the Messenger of Allah (peace and blessings be upon him) granted in the early days of Islam, but later he (peace and blessings be upon him) ordered to perform ghusl (ritual bath). Imam Darimi (may Allah have mercy on him) said: Another narrator said: Imam Zuhri (may Allah have mercy on him) said: The one whom I prefer narrated this hadith to me from Sayyiduna Sahl bin Sa’d (may Allah be pleased with him).
