Masruq reported: We went to Abdullah b. 'Amr when Mu'dwiya came to Kufa, and he made a mention of Messenger of Allah ﷺ and said: He was never immoderate in his talk and he never reviled others. Messenger of Allah ﷺ also said: The best amongst you are those who are best in morals. Uthman said: When he came to Kufa along with Mu'awiya... (The rest of the hadith is the same).

حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، وَعُثْمَانُ بْنُ أَبِي شَيْبَةَ، قَالاَ حَدَّثَنَا جَرِيرٌ، عَنِ الأَعْمَشِ،
عَنْ شَقِيقٍ، عَنْ مَسْرُوقٍ، قَالَ دَخَلْنَا عَلَى عَبْدِ اللَّهِ بْنِ عَمْرٍو حِينَ قَدِمَ مُعَاوِيَةُ إِلَى الْكُوفَةِ
فَذَكَرَ رَسُولَ اللَّهِ ﷺ فَقَالَ لَمْ يَكُنْ فَاحِشًا وَلاَ مُتَفَحِّشًا . وَقَالَ قَالَ رَسُولُ
اللَّهِ ﷺ
" إِنَّ مِنْ خِيَارِكُمْ أَحَاسِنَكُمْ أَخْلاَقًا " . قَالَ عُثْمَانُ حِينَ قَدِمَ
مَعَ مُعَاوِيَةَ إِلَى الْكُوفَةِ .
