It is narrated from Sayyiduna Anas (may Allah be pleased with him) that whenever the Prophet (peace and blessings be upon him) went out of the house for some task, he (peace and blessings be upon him) liked to hear: "O successful one! O rightly guided one!"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Hammad bin Salamah except Abu Amir; Muhammad bin Rafi' is alone in narrating it."
