Manifestations of the Truthfulness of Pronouncing the Two Testimonies

In reality, there are many questions regarding this topic, and it seems to me that there is nothing strange about that, Your Eminence. I ask: If you would be so kind, the pronunciation of the testimony undoubtedly has a truthfulness. What is the nature of that truthfulness, Your Eminence?
Answer: First, the command to pronounce the testimony is necessary. If one denies the pronunciation of it and does not pronounce it while he is able, he is a disbeliever until he pronounces the two testimonies; it is necessary. Then, along with the pronunciation, the belief and faith in the meaning of "La ilaha illa Allah" are necessary, which means that there is no deity worthy of worship in truth except Allah. So if he says it while lying, like the hypocrites, saying it while believing that there are other deities alongside Allah, this word does not benefit him, as He the Exalted said: [Al-Nisa: 145]. He the Exalted said: They deceive Allah and those who believe, but they do not deceive except themselves, and they do not perceive. [Al-Baqarah: 8-9]. So it is necessary to have conviction in the heart and certainty that there is no true deity except Allah, and it is necessary to purify worship for Allah, to love what it indicates of the oneness of Allah, and to hate disbelief and detest it. It is also necessary to accept the Shari'ah of Allah and submit to it. If he is arrogant about that and does not submit to the Shari'ah of Allah, he is a disbeliever, may Allah keep us safe. Yes.
The presenter: And this is the meaning of the negation and the affirmation, Your Eminence?
The Shaykh: Yes, its meaning is: there is no true deity except Allah. "La ilaha" means: negating divinity for other than Allah, meaning: believing that the divinity of other than Him is false. And "illa Allah" means: affirming servitude for Allah alone, and that He is the one who deserves it, as he (peace and blessings be upon him) said: : [Al-Hajj: 62], the verse from Surat al-Hajj, and its meaning is also in Surat Luqman. Yes.
The presenter: May Allah bless you. So the truthfulness of this testimony and this pillar of the pillars of Islam is acting upon the remaining pillars of Islam, the apparent and the hidden, which you have explained?
The Shaykh: Yes, yes, but they vary. Some, if left, result in disbelief, and some, if left, do not result in disbelief but result in incomplete faith and weak faith, unless he denies what Allah has made obligatory or denies what Allah has forbidden. If he denies it, he is a disbeliever according to all. If he denies the obligation of prayer, he is a disbeliever according to all. If he denies the obligation of fasting Ramadan, he is a disbeliever according to all. If he denies the obligation of zakah when its conditions are met, he is a disbeliever according to all. If he denies the obligation of Hajj when one is able, he is a disbeliever according to all. If he denies the prohibition of zina, he is a disbeliever according to all. If he denies the prohibition of intoxicants and says: it is not forbidden, he is a disbeliever according to all. If he denies undutifulness to parents and says: undutifulness to them is not forbidden, undutifulness to parents is permissible, he is a disbeliever by consensus, may Allah keep us safe. And so on with similar matters of the apparent things, matters of religion known by obligation or prohibition. Yes.
