Are the followed schools of jurisprudence a religious innovation?

The Shaykh : Well, he is asking about the schools of jurisprudence: are they a religious innovation or not?
We say: The schools of jurisprudence are the statements of the imams among the scholars of the Muslims, and they are opinions. However, the religious innovation is the fanaticism for a school of jurisprudence such that one does not accept anything other than it, even if it is the truth. This is what is not permissible. Because it is obligatory for a person, when the truth becomes clear to him, to follow it, whether it is in accordance with his school of jurisprudence or contrary to his school of jurisprudence. But the people of knowledge adopt these schools of jurisprudence in order to adopt their principles only, not to make them a proof for them before Allah. So when the truth becomes clear to them, they must return to it. Because Allah says: He did not say: What did you have to do? Did you have to follow Ahmad ibn Hanbal, or Muhammad ibn Idris, or Malik ibn Anas, or al-Nu'man Abu Hanifah? Never. Rather, Allah the Exalted said: So the religious innovation is for people to divide because of these schools of jurisprudence, such that I do not accept what is in your school of jurisprudence of truth, and you do not accept what is in my school of jurisprudence of truth. As for if a person returns to the truth, there is nothing wrong with him affiliating with a school of jurisprudence in order to build his principles upon it, but he takes the truth when it becomes clear to him.
