It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When will I meet my brothers?" The Companions (may Allah be pleased with them) said: "O Messenger of Allah! Are we not your brothers?" He (peace and blessings be upon him) said: "You are my Companions; my brothers are those who will believe in me although they will not have seen me."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Thabit al-Bunani except Muhtasib bin Abd al-Rahman; Abu Ubaydah al-Haddad is alone in narrating it."
