﴿ ٱلشَّهْرُ ٱلْحَرَامُ بِٱلشَّهْرِ ٱلْحَرَامِ وَٱلْحُرُمَٰتُ قِصَاصٌۭ ۚ فَمَنِ ٱعْتَدَىٰ عَلَيْكُمْ فَٱعْتَدُوا۟ عَلَيْهِ بِمِثْلِ مَا ٱعْتَدَىٰ عَلَيْكُمْ ۚ وَٱتَّقُوا۟ ٱللَّهَ وَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ مَعَ ٱلْمُتَّقِينَ ﴾

“Fight during the sacred months if you are attacked: for a violation of sanctity is [subject to the law of] just retribution. Thus, if anyone commits aggression against you, attack him just as he has attacked you - but remain conscious of God, and know that God is with those who are conscious of Him.”

(The forbidden month) in which you entered to perform the lesser pilgrimage ('umrah) (is for the forbidden month) which they prevented you from performing, (and forbidden things in retaliation) one in retaliation for another. (And one who attacketh you) first, in the Sacred Precinct (attack him in like manner as he attacked you) by killing them. (And observe your duty to Allah) and fear Allah to begin with, (and know that Allah is with those who ward off (evil)) He assists the pious by giving them victory.
