What kind of poetry is undesirable
حَدَّثَنَا أَبُو بَكْرٍ، حَدَّثَنَا حَفْصٌ، وَأَبُو مُعَاوِيَةَ وَوَكِيعٌ عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " لأَنْ يَمْتَلِئَ جَوْفُ الرَّجُلِ قَيْحًا حَتَّى يَرِيَهُ خَيْرٌ لَهُ مِنْ أَنْ يَمْتَلِئَ شِعْرًا " . إِلاَّ أَنَّ حَفْصًا لَمْ يَقُلْ يَرِيَهُ .
It was narrated from Abu Hurairah that the Messenger of Allah(ﷺ) 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."
