"The Messenger of Allah ﷺ commanded us to throw dust in the faces of those who praise others."  

أَمَرَنَا رَسُولُ اللَّهِ ﷺ أَنْ نَحْثُوَ فِي وُجُوهِ الْمَدَّاحِينَ التُّرَابَ  

"I heard the Messenger of Allah ﷺ say: 'Beware of praising one another, for it is slaughtering (one another).'"  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِيَّاكُمْ وَالتَّمَادُحَ فَإِنَّهُ الذَّبْحُ  

"A man praised another man in the presence of Messenger of Allah ﷺ. The Messenger of Allah ﷺ said: 'Woe to you,you have cut the neck of your companion,'several times. Then he said: 'If anyone of you praises his brother, let him say: "I think he is lie this, but I do not sanctify anyone before Allah."  

مَدَحَ رَجُلٌ رَجُلاً عِنْدَ رَسُولِ اللَّهِ ﷺ فَقَالَ رَسُولُ اللَّهِ ﷺ وَيْحَكَ قَطَعْتَ عُنُقَ صَاحِبِكَ مِرَارًا ثُمَّ قَالَ إِنْ كَانَ أَحَدُكُمْ مَادِحًا أَخَاهُ فَلْيَقُلْ أَحْسِبُهُ وَلاَ أُزَكِّي عَلَى اللَّهِ أَحَدًا
