It teaches Muslims to love one another, but to avoid making friends with outsiders, otherwise they will be 'one of their number.'
"Believers, take neither Jews nor Christians for your friends. They are friends with one another. Whoever of you seeks their friendship shall become one of their number. Allah does not guide the wrongdoers." (5:51, Quran)
So God doesnt guide the wrongdoers? Wow, thats a loving Allah isnt it?
The only wrongdoer is Muhammad, hes a false prophet.
