Takfiri is a scary word used to describe people who are extreme in their beliefs about religion. Takfiri people are people who think that anyone who believes in something different than their religion is wrong and must be punished or killed. Takfiris can treat people badly and even hurt them if they don't believe in their religion. It is important to remember that not all people who believe in a certain religion are like this and many people with different beliefs can be good friends or neighbors.
