Explanation of the two types of disbelief: doctrinal disbelief and practical disbelief

The Shaykh : Well, I say that it is established in the texts of the Book and the Sunnah that disbelief is divided into two categories: doctrinal disbelief. This is the type that takes its holder out of the religion, and if he says with his tongue "There is no god but Allah," he becomes a hypocrite and will be in the lowest depth of the Fire. He says "There is no god but Allah," but deep in his heart he disbelieves in "There is no god but Allah." So he says with his tongue what is not in his heart; what he says with his tongue, contrary to what is in his heart, does not benefit him with Allah in any way. This is doctrinal disbelief.
The student: Yes.

The Shaykh : Practical disbelief is that which testifies that there is no god but Allah, and naturally, the completion of the testimony is to the Messenger of Allah (peace and blessings be upon him), and to everything that the Messenger of Allah brought from Allah; he believes in all of that completely. But practically, he disbelieves in some of it, meaning he contradicts it, just as the disbelievers do. The disbelievers do not apply the rulings of Islam and do not judge by the Shari'ah of Islam. So this person who is a true monotheist in one or two or many, many characteristics, he does the deeds of the disbelievers, but he does not hold the belief of the disbelievers regarding what he does. For example, his saying (peace be upon him), which is established in "al-Sahihayn" from the hadith of Jarir ibn 'Abd Allah al-Bajali (may Allah be pleased with him), who said: , so if some Muslims stand up to strike the necks of others, this is naturally something forbidden in Islam. Please.
The student : Here, disbelief is known as minor disbelief and major disbelief. The hadith you cited, may Allah reward you with good, is minor disbelief, because what necessitates the fighting of a Muslim by a Muslim is disbelief, but what necessitates not applying the law of Allah (Glorified and Exalted is He) and making it general for... binding is disbelief. Many verses [support this], but I do not wish to mention them now. So your citation in the matter, O Shaykh, that striking the necks of Muslims by Muslims is a sin if one does not consider it permissible, but the citation here is regarding judging by other than what Allah revealed... Allah (Glorified and Exalted is He).

The Shaykh : Do I understand from your words that we agreed that there is practical disbelief and there is doctrinal disbelief? I do not think we agreed on this.
The student : ... .

The Shaykh : No problem, did we agree? If we agreed, we will shorten the path as I suggested before. And if we did not agree, I see now that your permission to speak was premature, because I have not finished yet. Your mind is free from this report and this detail, and I am saturated with this idea and have not yet expressed what I have.
