Mishkat al-Masabih 16 Retaliation كتاب القصاص 73

عَنْ أَبِي ذَرٍّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ كَشَفَ سِتْرًا فَأَدْخَلَ بَصَرَهُ فِي الْبَيْتِ قَبْلَ أَنْ يُؤْذَنَ لَهُ فَرَأَى عَوْرَةَ أَهْلِهِ فَقَدْ أَتَى حَدًّا لَا يَحِلُّ لَهُ أَنْ يَأْتِيَهُ وَلَوْ أَنَّهُ حِينَ أَدْخَلَ بَصَرَهُ فَاسْتَقْبَلَهُ رَجُلٌ فَفَقَأَ عَيْنَهُ مَا عَيَّرْتُ عَلَيْهِ وَإِنْ مَرَّ الرَّجُلُ عَلَى بَابٍ لَا سِتْرَ لَهُ غَيْرِ مُغْلَقٍ فَنَظَرَ فَلَا خَطِيئَةَ عَلَيْهِ إِنَّمَا الْخَطِيئَةُ عَلَى أَهْلِ الْبَيْتِ» . رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ غَرِيب

Abu Dharr reported God’s Messenger as saying, “If anyone removes a curtain and looks into a house before receiving permission and sees anything in those within which should not be seen, he has committed an offence which it is not lawful for him to commit. If a man confronted him when he looked in and put out his eye, I would not blame him; but if a man passes a door which has no curtain and is not shut and looks in, he has committed no sin, for the sin pertains only to the people inside.” Tirmidhi transmitted it, saying this is a gharib tradition.
