I am confused by something. I am doing homework on Islam for a religion class, and I’m reading something about Muhammad’s last sermon. In the article I’m reading every time they say his name they add, “Peace be upon him.” I’ve seen this in other places, too, like conversations on Wikipedia pages.
What’s the deal with this? Surely if he was the Prophet of God he’s in Heaven, right? Wouldn’t peace be pretty much automatic at that point? I understand it’s probably custom to add, “Peace be upon him” or “PBUH”, but just why? Can anyone clear this up for me?
