Is it obligatory for a person not to worship according to a specific school of jurisprudence? And does that necessitate abandoning the four schools of jurisprudence?

The questioner: My Shaykh, this is a question, and may Allah reward you, the issue has been clarified very well with our brother doctors, may Allah reward them with good; but in order to put the dots on the letters regarding a detail that is important in reality.

The Shaykh: Go ahead.
Al-Halabi: My Shaykh, when you say that it is not permissible to practice religion by following a school of jurisprudence and taking the four schools of jurisprudence as a religion, does this imply, or do we understand from this, that we should discard these four schools of jurisprudence and what we benefit from their knowledge?

The Shaykh: The answer to this was given previously with the doctor sitting next to me. I told him when he said to me that al-Khujandi says he takes from the Book and the Sunnah, and he added the word "only" and I held him accountable for it. Do you remember this?
Al-Halabi : Yes, yes.

The Shaykh: Why? Because he does not say this statement or any other, but rather the duty of the one who calls to Allah is to follow the Book of Allah and the Sunnah of the Messenger of Allah (peace and blessings be upon him), which is the foundation of this Islamic religion. That does not mean discarding the statements of the Companions, the statements of the Successors, or the statements of the jurists who exercised independent legal reasoning. On the contrary, I myself indicated that this statement is not correctly attributed to al-Khujandi, and we are the people most aware, by the grace of Allah, of the value of the statements of the scholars who came before us. Because among these statements, the least that can be said is that some are valid and some are not valid, some agree with the Book and the Sunnah and some do not agree with the Book and the Sunnah. This is because all scholars agree that the truth does not multiply. So when two differing statements come, one of us is forced to weigh the two statements. This weighing will open for him a path of research and thinking, and it was said long ago: "By their opposites, things become clear." Therefore, the call to return to the Book and the Sunnah for the scholars, and that the scholars must explain to people what Allah has revealed in the Qur'an and the Sunnah, does not mean discarding the statements of the Companions, the Successors, and the jurists who exercised independent legal reasoning. But it means, as our brother said previously, that we take from where they took. Where did they take from? They took from the Book and the Sunnah. So this is the answer to your question in brief: we make use of the statements of the scholars, the Companions, the Successors, and those who followed them, and the jurists who exercised independent legal reasoning, not just the four, but the forty, the four hundred, and the four thousand. Because the Islamic scholars, as Allah wills, contain a blessing as known by students of knowledge from the people of knowledge. We make use of the statements of these scholars to understand the most correct statements that agree with the Book and the Sunnah from what people have differed on. Have I answered you?
Al-Halabi : May Allah reward you.

The Shaykh: And perhaps after we have put the dots on the letters?
Al-Halabi : May Allah reward you with good.

The Shaykh : And beware of that.
