A sin is something that a religion tells its believers is a bad thing to do, usually because the thing is believed to draw people away from God and happiness.

Religions usually say that God told them that some things are sins through prophets (messengers from God). Usually the sacred books of a religion talk about sins. There are some things that most religions agree are sins. For example, almost every religion agrees that it is wrong to kill people (murder).

There are other things that are sins in only a few religions. For example, Muslims and Jews say that it is wrong to eat pork, but other religions do not think that it's wrong to eat this.

Most religions describe sins as actions that break their rules.
