Al-Adab Al-Mufrad, Hadith 860 ⓘ
Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "It is better for a man to fill his belly with oozing pus than to fill it with poetry."
حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ، قَالَ: حَدَّثَنَا أَبِي، قَالَ: حَدَّثَنَا الأَعْمَشُ قَالَ: سَمِعْتُ أَبَا صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللهِ صلى الله عليه وسلم: لَأَنْ يَمْتَلِئَ جَوْفُ رَجُلٍ قَيْحًا حَتَّى يَرِيَهُ، خَيْرٌ مِنْ أَنْ يَمْتَلِئَ شِعْرًا.
