Ask for permission before entering someone else's home or private space out of respect and courtesy towards them .

This hadith is about the importance of asking permission before entering someone's home. It was narrated by Ribi b. Hirash that a man asked the Prophet Muhammad ﷺ for permission to enter his house and he granted it to him. Similarly, other narrators such as Abu Dawud, Musaddad, Abu 'Awanah and Mansur also transmitted this hadith with slight variations in wording but with the same meaning - that one should always ask for permission before entering someone's home out of respect and politeness. This teaches us an important lesson in manners which is applicable even today - we should always ask for permission before entering someone else's home or private space out of respect and courtesy towards them.
