Sayyiduna Qurrah bin Iyas (may Allah be pleased with him) narrates: 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): "I love them both, so love them both!" (The narrator is unsure; perhaps the words are:) "O Allah, indeed I love them both, so love them both."
Al-Bazzar recorded it; its chain contains Ziyad bin Abi Ziyad, whom Ibn Hibban declared trustworthy, and he said: "He falls into error (wahm)." The remaining narrators of this report are thiqat (trustworthy).
