وَلَا تَسْتَوِي الْحَسَنَةُ وَلَا السَّيِّئَةُ ادْفَعْ بِالَّتِي هِيَ أَحْسَنُ فَإِذَا الَّذِي بَيْنَكَ وَبَيْنَهُ عَدَاوَةٌ كَأَنَّهُ وَلِيٌّ حَمِيمٌ
﴿٣٤﴾
سورة فصّلت
(41/34) And the good deed and the evil deed are not equal. Repel (evil) with what is best. Then the one whom you had enmity in between becomes as if he were a compassionate friend.
Surah Fussilat
