Al-Adab Al-Mufrad, Book 16, Hadith 2 (In-Book) ⓘ
Abu Musa reported that the Prophet, may Allah bless him and grant him peace, heard a man praise another man and he was using exaggeration in his praise of him. The Prophet, may Allah bless him and grant him peace, said, "You have destroyed - or broken - the man's back."
حَدَّثَنَا مُحَمَّدٍ، قَالَ: حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ، قَالَ: حَدَّثَنَا إِسْمَاعِيلُ بْنُ زَكَرِيَّا قَالَ: حَدَّثَنِي بُرَيْدُ بْنُ عَبْدِ اللهِ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِي مُوسَى قَالَ: سَمِعَ النَّبِيُّ صلى الله عليه وسلم رَجُلاً يُثْنِي عَلَى رَجُلٍ وَيُطْرِيهِ، فَقَالَ النَّبِيُّ صلى الله عليه وسلم: أَهْلَكْتُمْ، أَوْ قَطَعْتُمْ، ظَهْرَ الرَّجُلِ.
