Dividing disbelief into major and minor, explaining the six types of major disbelief, and discussing the first type, which is disbelief by denial.

Khalid al-Anbari: To begin: We have finished the topic of faith, albeit in a very brief manner, but given the time you have allowed us, we will proceed to the topic of declaring someone a disbeliever.
There is no doubt that disbelief is of two types: major disbelief and minor disbelief. The purpose of our discussion with you is major disbelief, which expels one from the religion. There is no doubt that disbelief which expels one from the religion, as held by the people of the Sunnah and the community, is of six types, not just one: "denial, rejection, stubbornness, hypocrisy, turning away, and doubt." Disbelief varied in this way because of the difference in people's positions toward the truth with which Allah sent the messengers and sent down the books. Some people disbelieve with their tongues and their hearts, and this is disbelief by denial. The majority of these people do not have a comprehensive understanding of what Allah has sent down; therefore, they disbelieved and denied. What points to this is the statement of our Lord: . And some people are certain in their hearts that it is the truth, but they conceal it and deny it with their tongues.
