Ask permission before entering someone's house

This hadith, narrated by Ibn 'Abbas and Abu Dawud, speaks to the importance of asking permission before entering someone's house. It is a sign of respect and humility to ask for permission before entering someone else’s home. The Prophet Muhammad commanded his slave-girl to ask for his permission when she wanted to enter his home, showing that this was an important practice even in the time of the Prophet himself. By following this practice, we can show our respect for others and their privacy.
