‘Amr ibn al-‘As reported: The Messenger of Allah, peace and blessings be upon him, would embrace the worst people with a cheerful face and kind words; by that he would soften their hearts. The Prophet would embrace me with a cheerful face and kind words, 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
