Sahih al-Bukhari, Book 78, Hadith 76 (In-Book) ⓘ
Narrated Anas: Allah's Messenger was neither a Fahish (one who had a bad tongue) nor a Sabbaba (one who abuses others) and he used to say while admonishing somebody, "What is wrong with him? May dust be on his forehead!"
حَدَّثَنَا مُحَمَّدُ بْنُ سِنَانٍ، حَدَّثَنَا فُلَيْحُ بْنُ سُلَيْمَانَ، حَدَّثَنَا هِلاَلُ بْنُ عَلِيٍّ، عَنْ أَنَسٍ، قَالَ لَمْ يَكُنْ رَسُولُ اللَّهِ صلى الله عليه وسلم فَاحِشًا وَلاَ لَعَّانًا وَلاَ سَبَّابًا، كَانَ يَقُولُ عِنْدَ الْمَعْتَبَةِ " مَا لَهُ، تَرِبَ جَبِينُهُ " .
