Bishr ibn al-Walid al-Kindi narrated to us, Abu Ma'shar narrated to us, from Mus'ab ibn Thabit, from Muhammad ibn al-Munkadir, from Abu Burdah ibn Abi Musa, from Abu Musa, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "There is no believer but that he will come on the Day of Resurrection with a Jew or a Christian, and it will be said: 'This is your ransom from the Fire.'"
