Calling bad names and cursing
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 ".
Narrated Anas: Allah's Messenger (ﷺ) 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!"
