Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) said: We were travelling with the Prophet (peace and blessings be upon him) at a place called al-Arj, when suddenly a poet appeared before us. He (peace and blessings be upon him) said: "Seize the Shaytan, for a man's belly being filled with pus is better than its being filled with poetry."
