It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) entered into his prayer and we also said the takbir with him. Then he (peace and blessings be upon him) signalled to the people: "Stay as you are." So we remained standing until the Prophet of Allah (peace and blessings be upon him) came to us; he (peace and blessings be upon him) had taken a ritual bath (ghusl) and water was dripping from his (peace and blessings be upon him) blessed head.
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Qatadah except Sa'id, and no one from Sa'id except Mu'adh; Ubaydullah bin Mu'adh is alone in narrating it."
