Sahih al-Bukhari, Hadith 6154 ⓘ
Narrated Ibn `Umar: The Prophet said, "It is better for a man to fill the inside of his body with pus than to fill it with poetry."
حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى، أَخْبَرَنَا حَنْظَلَةُ، عَنْ سَالِمٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لأَنْ يَمْتَلِئَ جَوْفُ أَحَدِكُمْ قَيْحًا خَيْرٌ لَهُ مِنْ أَنْ يَمْتَلِئَ شِعْرًا " .
