Surah Al-Baqarah, Verse 194

ٱلشَّهۡرُ ٱلۡحَرَامُ بِٱلشَّهۡرِ ٱلۡحَرَامِ وَٱلۡحُرُمَٰتُ قِصَاصٞۚ فَمَنِ ٱعۡتَدَىٰ عَلَيۡكُمۡ فَٱعۡتَدُواْ عَلَيۡهِ بِمِثۡلِ مَا ٱعۡتَدَىٰ عَلَيۡكُمۡۚ وَٱتَّقُواْ ٱللَّهَ وَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ مَعَ ٱلۡمُتَّقِينَ١٩٤

al-shahru l-ḥarāmu bil-shahri l-ḥarāmi wal-ḥurumātu qiṣāṣun famani iʿ'tadā ʿalaykum fa-iʿ'tadū ʿalayhi bimith'li mā iʿ'tadā ʿalaykum wa-ittaqū l-laha wa-iʿ'lamū anna l-laha maʿa l-mutaqīna

[Battle in] the sacred month is for [aggression committed in] the sacred month, and for [all] violations is legal retribution. So whoever has assaulted you, then assault him in the same way that he has assaulted you. And fear Allāh and know that Allāh is with those who fear Him.
