Respecting another person’s privacy begins before entering their home or room. Knocking is one part of that courtesy; identifying oneself when asked is another.
Example 1: When asked “Who is there?”, replying “I am Ahmad; I have come to see you” is informative.
Example 2: At an office, knock and wait for an invitation before entering a closed room.
Example 3: If there is no immediate answer, avoid disturbing people with repeated loud knocks.
The report does not prescribe one fixed phrase in all situations. Its core teaching is clear identification and respectful permission.
