The narrator said: I saw al-Ahnaf bin Qays narrating a hadith to his paternal uncle, and his uncle was Sayyiduna Jariyah bin Qudamah (may Allah be pleased with him), and he was sitting with Ibn Abbas (may Allah be pleased with them both). He said: O Messenger of Allah, tell me something that will benefit me, and keep it brief so that I can understand it. He (peace and blessings be upon him) said: "Do not become angry." Then he repeated his request, and he (peace and blessings be upon him) again said: "Do not become angry."
