Greeting people with peace & mercy of Allah

This hadith speaks about the importance of greeting people with peace and mercy of Allah. It was narrated by Abdullah that he saw the Messenger of Allah greet people every time he went down or came up, or stood or sat. He would say “As-salamu 'alaykum wa rahmatullah” which means “peace be upon you and the mercy of Allah” until his cheeks became white from repeating it so much. Similarly Abu Bakr and Umar also did this to show their respect for others. This hadith teaches us to always greet each other with peace and kindness as it is a sign of respect for one another in Islam. We should also remember that we are all equal in front of God no matter who we are talking to so we should treat everyone equally with respect regardless if they are our friends or strangers.
