Greet each other in a polite manner as it is a sign of respect for one another. Show kindness to those around you no matter who they are or where they come from.

This hadith is about the importance of greeting people with peace and mercy. The Prophet Muhammad was known for his kindness and politeness towards others. He would greet people on both sides of him by saying “As-salamu 'alaykum wa rahmatullah” which means “Peace be upon you and the mercy of Allah” until the whiteness of his cheeks could be seen. This hadith teaches us that we should always greet each other in a polite manner as it is a sign of respect for one another. It also shows us that we should always show kindness to those around us no matter who they are or where they come from.
