Al-Adab Al-Mufrad, Hadith 1068 ⓘ
Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, "If a man looks into your house and you take some pebbles and gouge out his eye, there is no fault in you."
حَدَّثَنَا أَبُو الْيَمَانِ، قَالَ: أَخْبَرَنَا شُعَيْبٌ، قَالَ: حَدَّثَنَا أَبُو الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ: لَوْ اطَّلَعَ رَجُلٌ فِي بَيْتِكَ، فَخَذَفْتَهُ بِحَصَاةٍ فَفَقَأْتَ عَيْنَهُ، مَا كَانَ عَلَيْكَ جُنَاحٌ.
