Abu Sa'id Khudri reported that Messenger of Allah ﷺ was more modest than the virgin behind the curtain (or in the apartment), and when he disliked anything, we recognised that from his face.  

سَمِعْتُ أَبَا سَعِيدٍ الْخُدْرِيَّ يَقُولُ كَانَ رَسُولُ اللَّهِ ﷺ أَشَدَّ حَيَاءً مِنَ الْعَذْرَاءِ فِي خِدْرِهَا وَكَانَ إِذَا كَرِهَ شَيْئًا عَرَفْنَاهُ فِي وَجْهِهِ  

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).  

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  

This hadith had been narrated on the authority of al-A'mash through another chain of transmitters also.  

عَنِ الأَعْمَشِ بِهَذَا الإِسْنَادِ مِثْلَهُ
