«مَا الْمَكْرُ بِالْمُحْصَنَاتِ مِنْ خُلُقِي»
Deceiving respectable women is not my character.
Mā al-makru ... min khuluqī is a general denial of deceptive character, not documentary proof about a particular incident. The husband also denies concealment and lying as habitual practices.
Such a defence can influence the listener’s assessment of credibility, but it does not automatically resolve every factual complaint from the wife. The construction places the negation at the level of self-characterization rather than independently verified evidence.
Practice: Does “I am not deceptive” conclusively refute each specific allegation? No.
