Sure 16 Al-Nahl (The Bee), vers 126

1. وَإِنْ عَاقَبْتُمْ فَعَاقِبُوا بِمِثْلِ مَا عُوقِبْتُمْ بِهِ ۖ وَلَئِنْ صَبَرْتُمْ لَهُوَ خَيْرٌ لِلصَّابِرِينَ

   And if you punish (an enemy, O believers), punish with an equivalent of that with which you were harmed. But if you are patient - it is better for those who are patient.

   16:126
