Hadith 31-77

وَبِهذَا الإِسنادِ قالَ: قالَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَآلِهِ: رَأْسُ العَقلِ بَعْدَ الإِيمان بِاللَّهِ التَّوَدُّدُ إِلَى النَّاسِ وَاصطِناعُ الخَيْرِ إِلى كُلِّ [احَدٍ] بَرٍّ وَفاجِرٍ.

According to the same documentation, God’s Prophet (S) said, “The most intelligent thing after faith is treating the people with kindness. Do good to all people whether they are good or bad.”
