I've done that before, I had to read some of the Quran, which was interesting, because it has Jesus in it, but he's just a prophet, not the son of God, and yes, it mentions severly punishing those who don't believe in the Quran, but the Bible also talks about such things. The Islamic religion doesn't centre around violence. They are actually quite peaceful. There are radicalists, people who take it to the extreme, and those are the people who kill and such, and that's why people who follow the Islamic religion get a bad rep.
But there are radicalists for any religion, Christianity included. Those radicalist preach that no one deserves mercy and they all deserve to burn in hell. Some examples are Westboro baptist church (CrINgE) And Pastor Johnathan Edwards, which was forever ago, but he did 'Sinners in the hands of an angry god." Which pretty much taught that god hates everyone and he only saves a select few.
What I was trying to say, is it's interesting that Jesus s portrayed as a Prophet, and not all God, all human, because, if you norice, it does indeed nod to the presence of Jesus in history, but doesn't mention the god prt, much like the Jewish people. They agree that Jesus was a prophet and that he was real, but they also believe that he was't the son of god. I just think that's interesting~
