What is the Judgment for a Wajib?

The judgment for a wajib is like a fard. That is, when a wajib is fulfilled, rewards are obtained; when it is abandoned, the person who abandons it is punished. However, a person who denies a wajib is not regarded to have exited Islam. However, he is regarded to have committed a bid’ah and a sin because he has denied an order of the religion.
