Abu Sa‘d says that a man came to Sayyiduna Ibn ‘Amr (may Allah be pleased with him) and said, "I ask you about the hadith which you yourself heard from the Prophet (peace and blessings be upon him); I do not ask about what is in the Torah." He replied: "I heard the Prophet (peace and blessings be upon him) say: The true Muslim is the one from whose tongue and hand other Muslims are safe."
