Islam
Islam is the religion of Muslims.
It is based on the teachings of the Qur’an. Muslims believe that the Archangel Gabriel delivered the words of the Qur’an to the Prophet Muhammad beginning in 610 A.D.
Muslims believe that anyone who does not believe in their religion is an infidel. Their most hated enemies are Jews and Christians. With a few exceptions, Muslims are peaceful until they become the majority in a nation. Then they begin to persecute and kill infidels.
Saudi Arabia has two cities (Medina & Mecca) that infidels are not even allowed to enter. Entrance is punishable by death.
