Mukhtasar Bukhari (Abridged) 2048 — Being overly occupied with poetry

Narrated Ibn Umar (may Allah be pleased with them) that the Prophet (peace and blessings of Allah be upon him) said: "If the belly of any one of you were to be filled with pus, it would be better for him than to be filled with poetry." (That is, if he remembers only poetry and nothing else, and especially those verses which are against the Shariah.)
