It is noted in a Hadith that
The prophet Muhammad (peace be upon him) and several of his companions were sitting down along a street in Medina.Suddenly a companion spotted a funeral procession approaching the group.In respect of the dead human body, Muhammad (pbuh) stood up as the procession crossed in front of him.At the moment, a component who was still sitting down said to the prophet,'this is a funeral of a jew.He is not a Muslim."upon hearing these words, Muhammad (pbuh) became upset and said back to the companion,'Is he not a human body?'

The message is very clear: prophet Muhammad sallallahu alaihissalam respected human beings irrespective of their religion. He taught mankind that every human soul is important weather alive or dead .This is Muhammads concept of dignity .He defended humanity.
so we should all follow the prophet,try to learn more and more about him.May Allah swt.guide and protect all of us ,Ameen.
