Abu Sa`id Al-Khudri reported: We were going with Allah's Messenger (ﷺ). As we reached the place (known as) `Arj there met (us) a poet who had been reciting poetry. Thereupon Allah's Messenger (ﷺ) said: Catch the satan or detain the satan, for filling the belly of a man with pus is better than stuffing his brain with poetry.
