a prohibited month is to be respected if the same is respected and likewise there is the law of just retribution for the violation of all prohibited things. therefore if anyone transgresses a prohibition by attacking you you may do likewise but always fear aiiah and bear in mind that allah is with those who desist from breaking allahs bounds.
الشهر الحرام بالشهر الحرام والحرمات قصاص فمن اعتدى عليكم فاعتدوا عليه بمثل ما اعتدى عليكم واتقوا الله واعلموا أن الله مع المتقين
