See hadith 858.  

عَنِ النَّبِيِّ ﷺ قَالَ مِنَ الشِّعْرِ حِكْمَةٌ  

'Abdullah ibn 'Amr reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "Poetry is in the same position as speech. The good of it is like good words and its bad part is like bad words."  

قَالَ رَسُولُ اللهِ ﷺ الشِّعْرُ بِمَنْزِلَةِ الْكَلاَمِ حَسَنُهُ كَحَسَنِ الْكَلامِ وَقَبِيحُهُ كَقَبِيحِ الْكَلامِ  

'A'isha said, "Poetry is both good and bad. Take the good and leave the bad. I have related some of the poetry of Ka'b ibn Malik. That included an ode of forty verses and some less than that."  

أَنَّهَا كَانَتْ تَقُولُ الشِّعْرُ مِنْهُ حَسَنٌ وَمِنْهُ قَبِيحٌ خُذْ بِالْحَسَنِ وَدَعِ الْقَبِيحَ وَلَقَدْ رَوَيْتُ مِنْ شِعْرِ كَعْبِ بْنِ مَالِكٍ أَشْعَارًا مِنْهَا الْقَصِيدَةُ فِيهَا أَرْبَعُونَ بَيْتًا وَدُونَ ذَلِكَ  

See hadith 859.  

حَدَّثَهُ قَالَ كُنْتُ شَاعِرًا فَقُلْتُ يَا رَسُولَ اللهِ امْتَدَحْتُ رَبِّي فَقَالَ أَمَا إِنَّ رَبَّكَ يُحِبُّ الْحَمْدَ وَمَا اسْتَزَادَنِي عَلَى ذَلِكَ
