عَنْ أَبِي مُوسَى الْأَشْعَرِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ سَمِعَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ رَجُلًا يُثْنِي عَلَى رَجُلٍ وَيُطْرِيهِ فِي الْمِدْحَةِ فَقَالَ لَقَدْ أَهْلَكْتُمْ أَوْ قَطَعْتُمْ ظَهْرَ الرَّجُلِ
It is narrated from Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) heard a man praising another man and exaggerating in it. The Prophet (peace and blessings be upon him) said: "You have destroyed this man's back, or you have cut it."
