It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he said: "I heard the Messenger of Allah (peace and blessings be upon him) say: 'Whoever gives his pledge of allegiance and then breaks it will meet Allah, the Mighty and Majestic, on the Day of Resurrection without his right hand being with him.'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Musa except Muhammad bin Ma'n, and Ibrahim bin al-Mundhir is alone in narrating it."
