Al-Adab Al-Mufrad, Book 36, Hadith 10 (In-Book) ⓘ

'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."

حَدَّثَنَا مُحَمَّدُ بْنُ سَلامٍ، قَالَ‏:‏ حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَيَّاشٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ زِيَادِ بْنِ أَنْعُمٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ رَافِعٍ، عَنْ عَبْدِ اللهِ بْنِ عَمْرٍو قَالَ‏:‏ قَالَ رَسُولُ اللهِ صلى الله عليه وسلم‏:‏ الشِّعْرُ بِمَنْزِلَةِ الْكَلاَمِ، حَسَنُهُ كَحَسَنِ الْكَلامِ، وَقَبِيحُهُ كَقَبِيحِ الْكَلامِ‏.‏
