Abu Hurayra reported that the Prophet ﷺ said, "If a man looks into your house and you take some pebbles and gouge out his eye, there is no fault in you."

عَنِ النَّبِيِّ ﷺ قَالَ لَوْ اطَّلَعَ رَجُلٌ فِي بَيْتِكَ فَخَذَفْتَهُ بِحَصَاةٍ فَفَقَأْتَ عَيْنَهُ مَا كَانَ عَلَيْكَ جُنَاحٌ

Anas said, "The Prophet ﷺ was standing in prayer and a man looked into his room. He took an arrow from his quiver and aimed it at his eyes."

عَنْ أَنَسٍ قَالَ كَانَ النَّبِيُّ ﷺ قَائِمًا يُصَلِّي فَاطَّلَعَ رَجُلٌ فِي بَيْتِهِ فَأَخَذَ سَهْمًا مِنْ كِنَانَتِهِ فَسَدَّدَ نَحْوَ عَيْنَيْهِ
