If a person denies anything that is established in the Book and the Sunnah, does that make him a disbeliever?

The Shaykh : I return to the brother here when he said—regarding the one who said, "I said it and you repeated it"—that prayer is regressive. This statement indicates what is in his heart, which is that he denied what is established in Islam. Here, too, there is a point that deserves clarification: Does a person become a disbeliever merely by denying anything, whatever it is, that is established in the Book and the Sunnah? Did he deny it? Is anything that a Muslim denies from what is established in the Book and the Sunnah considered denial?
The answer is: No. A person only becomes a disbeliever by denying what he knows of Islam. As for if he denies something that I say is part of Islam, and he says, "No, this is not part of Islam," and he says to me, for example, "What is your proof?" I say to him, "The hadith of the Messenger of Allah (peace and blessings be upon him)." He says to me, "This hadith is not authentic." I say to him, "No, al-Bukhari narrated it." He says to me, "What, is al-Bukhari infallible?!" He has doubts, he has suspicions, and so on. I do not declare this person a disbeliever, even though he disagrees with me.
We know that great scholars in the present era and before the present era deny authentic hadiths agreed upon by Muslim scholars, especially the hadith scholars, yet we do not declare them disbelievers. And you, along with Sayyid Qutb, in his interpretation of the Mu'awwidhat at the end of the Qur'an, deny the hadith of the sorcery of the Messenger of Allah (peace and blessings be upon him), and that the Messenger of Allah (peace and blessings be upon him) said that Allah (Mighty and Majestic) informed him about the cause of his illness and the sorcery, and so on. Sayyid Qutb denies this hadith; do we declare him a disbeliever? It is not permissible to declare him a disbeliever. Other people deny established beliefs in the Qur'an; because someone from you will now say, "This is a hadith, and the establishment of a hadith is based on opinion, and it is subject to doubt, and so on." But from where does he bring in doubt to deny what is in the Qur'an? He brings in doubt to deny what is in the Qur'an through the aspect of figurative interpretation.
Therefore, the Islamic sects went astray: the Jahmiyyah, the Mu'tazilah, the Jabriyyah, the Khawarij, and so on. There is no Muslim on the face of the earth who says that the saying of Allah (Mighty and Majestic): is not a noble verse. No Muslim says this. But there are Muslims who say: "Allah is not seen on the Day of Resurrection," even though Allah says: . He tells you: "You did not understand its meaning; its meaning is , meaning: to the pleasure of her Lord, with a suppressed additional qualifier. These people, although they are misguided, the people of tawhid (the oneness of Allah) did not rule that they are apostates from their religion; why? Because they have a doubt, they have an excuse. Therefore, disbelief, first, is established by denial, and second, by denying what is known from the religion by necessity. This is a scientific expression, not merely that a Muslim denied anything from the known Shari'ah and is ruled to be an apostate from his religion; no, rather, if he denies what is known from the religion by necessity, then he is an apostate.
As for His saying: , there has been disagreement in it since ancient times, and this disagreement has continued to this day until it became a matter of disagreement in the beliefs. And today, the majority of Muslims do not believe that the Most Merciful rose above the Throne, so I do not think any of you would say: "They do not believe that Allah said: ." These are numerous verses in the Qur'an with this meaning and this wording, . They do not believe that the Most Merciful rose above the Throne in the sense of rising above it, as is the figurative interpretation or explanation of the righteous Salaf, but rather they have distorted interpretations that deviate from the path of the Salaf. So were they declared disbelievers?! ...
