‘Amr ibn al-‘As reported: The Messenger of Allah, peace and blessings be upon him, would meet even the worst people with eye contact and speak at their level, by which he would show friendliness to them. The Prophet would meet me with eye contact and speak at my level, until I thought that I was the best of people.

عَنْ عَمْرِو بْنِ الْعَاصِ قَالَ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُقْبِلُ بِوَجْهِهِ وَحَدِيثِهِ عَلَى أَشَرِّ الْقَوْمِ يَتَأَلَّفُهُمْ بِذَلِكَ فَكَانَ يُقْبِلُ بِوَجْهِهِ وَحَدِيثِهِ عَلَيَّ حَتَّى ظَنَنْتُ أَنِّي خَيْرُ الْقَوْمِ
