I was talking with a friend and we were talking about our religion, and the battle of khaybar got brought up and I asked if they knew what Muhammad PBUH did to the jews and I said he killed them (actually I used the word slaughter) and explained this wasn't a time to be lovey dovey. Then explained that prophets go to war and battles. Is this slandering the prophet? I really didn't mean to, and almost think I should go get the death penalty for this. I thought that's what happened, because even someone from my masjid said this. Must I go and receive the death penalty? I really need to keep my mouth shut.
