Musnad Abu Ya'la al-Mawsili 109:57

Al-Jarrah narrated to us, Ahmad ibn Sulayman al-Khurasani narrated to us, Ahmad ibn Mihraz al-Azdi narrated to us, from Muhammad ibn al-Munkadir, from Jabir, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "For the inside of one of you to be filled with pus or blood is better for him than for it to be filled with poetry by which he is satirized."
