Al Baqarah, 194 Ayah
2:194
ٱلشَّهۡرُ ٱلۡحَرَامُ بِٱلشَّهۡرِ ٱلۡحَرَامِ وَٱلۡحُرُمَٰتُ قِصَاصٞۚ فَمَنِ ٱعۡتَدَىٰ عَلَيۡكُمۡ فَٱعۡتَدُواْ عَلَيۡهِ بِمِثۡلِ مَا ٱعۡتَدَىٰ عَلَيۡكُمۡۚ وَٱتَّقُواْ ٱللَّهَ وَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ مَعَ ٱلۡمُتَّقِينَ ١٩٤
Ash-Shahru Al-Ĥarāmu Bish-Shahri Al-Ĥarāmi Wa Al-Ĥurumātu Qişāşun ۚ Famani A`tadá `Alaykum Fā`tadū `Alayhi Bimithli Mā A`tadá `Alaykum ۚ Wa Attaqū Al-Laha Wa A`lamū 'Anna Al-Laha Ma`a Al-Muttaqīna
[Fighting 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 Allah and know that Allah is with those who fear Him.
