Muslims maintain they were not written, they came directly from God. Also, Qur’an radically changed many moral values of the society at the time (most significant one being changing the state of polytheism from worship to blasphemy), and Muslims faced very strong and violent opposition because of that. I don’t know the specific subject of guns in E.T, but Islamic morality covers every single subject in life without exception. I didn’t say they are truth, I say there is one truth regarding their morality: They are either good or bad.
