Narrated Yahya: Humaid said, "A man peeped into the house of the Prophet and the Prophet aimed an arrow head at him to hit him." I asked, "Who told you that?" He said, "Anas bin Malik" (See Hadith No. 258 and 259, Vol. 8)

Narrated Sa`d: A man peeped into the house of the Prophet through a hole while the Prophet was scratching his head with a Midrai (a certain kind of comb). On that the Prophet said (to him), "If I had known you had been looking, then I would have pierced your eye with that instrument, because the asking of permission has been ordained so that one would not see things unlawfully."

Narrated Sahl bin Sa`d: A man peeped through a round hole into the dwelling place of the Prophet, while the Prophet had a Midray (an iron comb) with which he was scratching his head. the Prophet said, " Had known you were looking (through the hole), I would have pierced your eye with it (i.e., the comb)." Verily! The order of taking permission to enter has been enjoined because of that sight, (that one should not look unlawfully at the state of others). (See Hadith No. 807, Vol. 7)

Narrated Anas bin Malik: A man peeped into a room of the Prophet. The Prophet stood up, holding an arrow head. It is as if I am just looking at him, trying to stab the man.

And added, "If someone is peeping (looking secretly) into your house without your permission, and you throw a stone at him and destroy his eyes, there will be no blame on you."

Narrated Anas: A man peeped into one of the dwelling places of the Prophet. The Prophet got up and aimed a sharp-edged arrow head (or wooden stick) at him to poke him stealthily.

Narrated Sahl bin Sa'd As-Sa'idi: A man peeped through a hole in the door of Allah's Apostle's house, and at that time, Allah's Apostle had a Midri (an iron comb or bar) with which he was rubbing his head. So when Allah's Apostle saw him, he said (to him), "If I had been sure that you were looking at me (through the door), I would have poked your eye with this (sharp iron bar)." Allah's Apostle added, "The asking for permission to enter has been enjoined so that one may not look unlawfully (at what there is in the house without the permission of its people)."

Narrated Abu Huraira: Abul Qasim said, "If any person peeps at you without your permission and you poke him with a stick and injure his eye, you will not be blamed."
