It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) passed by two men who were performing Hajj tied (to each other) because of a vow. He (peace and blessings be upon him) said: "Undo this bond of yours." They both said: "O Messenger of Allah! It is a vow." The Messenger of Allah (peace and blessings be upon him) said: "Undo this bond of yours, then perform Hajj."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Muhammad bin Kurayb except Abu Zuhayr."
