Greeting those at graveyards with peace &wishingthemwellbeing .

This hadith is about how Prophet Muhammad taught people to greet those in the graveyard with peace and well being. He taught them to say "As salamu alaykum ahlad diyar minal muminina wal muslimin" which translates to "Peace be upon you O inhabitants of the abodes believers and Muslims". He also taught them to say "Wa inna insha Allah bikum lahiqun nasalul laha lana wa lakumul 'afiyah" which translates to "We will join you soon if Allah wills. We ask Allah for well being for us and for you". This hadith teaches us that we should always show respect towards those who have passed away by greeting them with peace and wishing them well being even though they are no longer here physically. It also teaches us that we should always have faith that one day we will all reunite again if it is God's will.
