Messenger of Allah ﷺ neither talked in an insulting manner nor did he ever speak evil intentionally. He used to say, "The most beloved to me amongst you is the one who has the best character and manners." He added, " Learn the Qur'an from (any of these) four persons. ʿAbdullah bin Masʿud, Salim the freed slave of Abu Hudhaifa, Ubai bin Kaʿb, and Muʿadh bin Jabal."
عَبْدُ اللَّهِ بْنُ عَمْرٍو إِنَّ رَسُولَ اللَّهِ ﷺ لَمْ يَكُنْ فَاحِشًا وَلاَ مُتَفَحِّشًا وَقَالَ إِنَّ مِنْ أَحَبِّكُمْ إِلَىَّ أَحْسَنَكُمْ أَخْلاَقًا وَقَالَ اسْتَقْرِئُوا الْقُرْآنَ مِنْ أَرْبَعَةٍ مِنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ وَسَالِمٍ مَوْلَى أَبِي حُذَيْفَةَ وَأُبَىِّ بْنِ كَعْبٍ وَمُعَاذِ بْنِ جَبَلٍ
