Hadith 3514

He told that he heard God’s Messenger say, “If anyone were to look into your house without receiving your permission and you were to throw a pebble at him and put out his eye, you would be guilty of no offence.” (Bukhari and Muslim)

وَعَنْهُ أَنَّهُ سَمِعَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «لَوِ اطَّلَعَ فِي بَيْتِكَ أحدٌ ولمْ تَأذن لَهُ فخذفته بحصاة ففتأت عَيْنَهُ مَا كَانَ عَلَيْكَ مِنْ جُنَاحٍ»
