Hadith 6001
Sayyiduna Sahl bin Sa’d Sa’idi (may Allah be pleased with him) narrates: A man peeped through a crack in the door of the Prophet’s (peace and blessings be upon him) house. At that time, the Prophet (peace and blessings be upon him) had a comb in his blessed hand and was scratching his head with it. When the Prophet (peace and blessings be upon him) saw him, he said: If I had known that you were looking at me, I would have poked it into your eye. Permission to enter has been enjoined so that (the household) may not be looked upon.
