Quran 16:126 — Surah An-Nahl, ayah 126

وَإِنۡ عَاقَبۡتُمۡ فَعَاقِبُواْ بِمِثۡلِ مَا عُوقِبۡتُم بِهِۦۖ وَلَئِن صَبَرۡتُمۡ لَهُوَ خَيۡرٞ لِّلصَّـٰبِرِينَ

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

Ako hoćete da na nepravdu uzvratite, onda učinite to samo u onolikoj mjeri koliko vam je učinjeno; a ako otrpite, to je, doista, bolje za strpljive.
