Narrated Masruq:
حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ ، حَدَّثَنَا أَبِي ، حَدَّثَنَا الأَعْمَشُ ، قَالَ حَدَّثَنِي شَقِيقٌ ، عَنْ مَسْرُوقٍ ، قَالَ كُنَّا جُلُوسًا مَعَ عَبْدِ اللَّهِ بْنِ عَمْرٍو يُحَدِّثُنَا إِذْ قَالَ لَمْ يَكُنْ رَسُولُ اللَّهِ صلى الله عليه وسلم فَاحِشًا وَلاَ مُتَفَحِّشًا، وَإِنَّهُ كَانَ يَقُولُ " إِنَّ خِيَارَكُمْ أَحَاسِنُكُمْ أَخْلاَقًا " .
We were sitting with `Abdullah bin `Amr who was narrating to us (Hadith): He said, "Allah's Messenger (ﷺ) was neither a Fahish nor a Mutafahhish, and he used to say, 'The best among you are the best in character (having good manners)."'
