Do you like to eat the flesh of your dead brother's body?

if you don't want to eat your dead brother's body do not backbite one another.
Allah says in Quran:
And do not spy on one another or backbite. Will any of you love to eat the flesh of his dead brother? You would hate it. Be wary of Allah; indeed Allah is all-clement, all-merciful.
(the Surah 49, verse 12)
