It is reported from him: The Prophet (peace and blessings be upon him) said about Sayyiduna Imam Hasan (may Allah be pleased with him) and Sayyiduna Imam Husayn (may Allah be pleased with him): "O Allah, I love them both, so love them both! And whoever loves them both loves me."
Al-Bazzar recorded it, and its chain is good.
