Ibn 'Umar reported that the Prophet, may Allah bless him and grant him peace, said, "It is better for one of you to fill his belly with pus than to fill it with poetry."  

عَنِ النَّبِيِّ ﷺ قَالَ لأَنْ يَمْتَلِئَ جَوْفُ أَحَدِكُمْ قَيْحًا خَيْرٌ لَهُ مِنْ أَنْ يَمْتَلِئَ شِعْرًا  

In respect of "And as for the poets, is the misled who follow them. Do you not see how they ramble on in every style and that they say things which they do not do?" (26:223-225), Ibn 'Abbas said that it was abrogated and that an exception was made in His words, "except for those who believe and do right actions the kind of reversal they will receive." (26:226)  

عَنِ ابْنِ عَبَّاسٍ {وَالشُّعَرَاءُ يَتَّبِعُهُمُ الْغَاوُونَ} إِلَى قَوْلِهِ {وَأَنَّهُمْ يَقُولُونَ مَا لاَ يَفْعَلُونَ} فَنَسَخَ مِنْ ذَلِكَ وَاسْتَثْنَى فَقَالَ {إِلاَّ الَّذِينَ آمَنُوا} إِلَى قَوْلِهِ {يَنْقَلِبُونَ}
