AN NAHL (LEBAH) — Ayat 126

وَإِنْ عَاقَبْتُمْ فَعَاقِبُواْ بِمِثْلِ مَا عُوقِبْتُم بِهِ وَلَئِن صَبَرْتُمْ لَهُوَ خَيْرٌ لِّلصَّابِرينَ

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.
