Ask for permission before entering someone else’s home or any other public place.

This hadith is about the importance of seeking permission before entering someone's house. It was narrated by Kildah bin Al-Hanbal, who visited the Prophet Muhammad ﷺ and entered his house without seeking permission first. The Prophet ﷺ then told him to go back and ask for permission by saying "As-Salamu 'alaikum" which means "may peace be upon you". This hadith teaches us that we should always show respect and etiquette when entering someone else's home, as it is a sign of politeness and good manners. We should always remember to ask for permission before entering any place, whether it be a friend or family member's home or even a public place such as a mosque or school.
