ذِكْرُ الزَّجْرِ عَنْ طَلَبِ الْمَرْءِ عَثَرَاتِ أَهْلِهِ أَوْ تَقَصُّدِ خِيَانَتِهِمْ
The Messenger of Allah ﷺ forbade that a man should come to his family like (an unexpected) night visitor doubting their fidelity and spying into their lapses. (Using translation from Muslim 715ab)
«نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يَطْرُقَ الْمَرْءُ أَهْلَهُ لَيْلًا أَوْ يُخَوِّنَهُمْ وَيَلْتَمِسَ عَثَرَاتِهِمْ»
