[Battle in] the sacred month is for [aggression committed in] the sacred month,1 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.
Translation: Saheeh International (English)
1 The sacred months are Dhul-Qaʿdah, Dhul-Ḥijjah, Muḥarram and Rajab.

Tafsir
The sacred month in which Allah allowed you to enter the Sacred Mosque and perform Umrah in the seventh year after the Migration is a compensation for the sacred month when you were stopped by the idolaters from entering the Sacred Mosque in the sixth year after the Migration. The law of equality applies when the limits are overstepped in regards to sacred things, such as the sacred land, the sacred month and being in an ordered state of purity (iḥrām) for pilgrimage to the Sacred Mosque. When someone wrongs you in any of these, treat them as they treated you, but do not go beyond what they have done: Allah does not love those who overstep His limits. Be mindful of Allah by not going beyond what He has given you permission to do. Know that Allah is with those who are mindful of Him, giving them success and supporting them.
