Sunan Ibn Majah, Volume 5, Book 33, Hadith 3760 (DarusSalam) ⓘ
It was narrated from Sad bin Abu Waqas that the Prophet said: "If a man were to fill his stomach completely with pus until it destroyed him, that would be better for him than filling (his mind) with poetry."
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، وَمُحَمَّدُ بْنُ جَعْفَرٍ، قَالاَ حَدَّثَنَا شُعْبَةُ، حَدَّثَنِي قَتَادَةُ، عَنْ يُونُسَ بْنِ جُبَيْرٍ، عَنْ مُحَمَّدِ بْنِ سَعْدِ بْنِ أَبِي وَقَّاصٍ، عَنْ سَعْدِ بْنِ أَبِي وَقَّاصٍ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ قَالَ " لأَنْ يَمْتَلِئَ جَوْفُ أَحَدِكُمْ قَيْحًا حَتَّى يَرِيَهُ خَيْرٌ لَهُ مِنْ أَنْ يَمْتَلِئَ شِعْرًا " .
