Sahl bin Sad as-Said reported that a person peeped through the hole of the door of Allahs Messenger ﷺ , and at that time Allahs Messenger ﷺ had with him a scratching instrument with which he had been scratching his head. When Allahs Messenger ﷺ saw him. He said: If I were to know that you had been peeping through the door, I would have thrust that into your eyes, and Allahs Messenger ﷺ said: Permission is needed as a protection against glance.
