Do they know that rciting the first pillar in public makes you a Muslim in the eyes of Islam? You say the Shahada, I testify “La ilaha illa Allah, Muhammad rasoolu Allah.”
These Arabic words mean, “There is no true god (deity) but God (Allah), and Muhammad is the Messenger (Prophet) of God.” Once a person says the Testimony of Faith (Shahada) with conviction and understanding its meaning, then he/she has become a Muslim.
...and if you try to leave, you can be lawfully killed for apostasy. Welcome to the Roach Motel.
