Greet others warmly using "As-salamu 'alaykum wa rahmatullah" which translates to "Peace be upon you and the mercy of Allah".

This hadith is about the importance of greeting others with peace and mercy of Allah. It was narrated by Abdullah that the Prophet said, “It is as if I can see the whiteness of his cheek, saying to his right As-salamu 'alaykum wa rahmatullah and to his left As-salamu 'alaykum wa rahmatullah”. This means that when we greet someone, we should say “As-salamu 'alaykum wa rahmatullah” which translates to “Peace be upon you and the mercy of Allah”. By doing this, we are showing respect for each other as well as expressing our faith in God's mercy. We should always strive to spread peace in our lives by greeting each other warmly with these words.
