Abu Wahb reported: Abdullah ibn Mubarak, may Allah be pleased with him, described good character saying, “It is a smiling face, doing your best in what is good, and refraining from harm.”
[Sunan At-Tirmidhi, Book of Righteousness, Number 2005, Sahih]

عَنْ عَبْدِ اللَّهِ بْنِ الْمُبَارَكِ أَنَّهُ وَصَفَ حُسْنَ الْخُلُقِ فَقَالَ هُوَ بَسْطُ الْوَجْهِ وَبَذْلُ الْمَعْرُوفِ وَكَفُّ الْأَذَى
