i put it up for a vote to see what others think. 
perhaps we could use his hebrew or greek name, but i believe english is wrong. i think a lot of english speakers forget it’s not the only language (even i do sometimes), it wasn’t even the language the bible was originally in.
no, i didn’t add relationships (yet), but i did explain why i added him. he probably has many dedicated works that should be added as relationships. he exists in mb for the exact same reason jesus does, there just hasn’t been relationships added yet. by adding him, he already exists, so anyone who wants to add a relationship doesn’t have to add a whole new artist.
yes, they should definitely have “person”. it’s been proven by historians that jesus and muhammad exist. the actual story of their lives are debated, but they are definitely people.
