What is meant by the book (Lamadhhabiyah: The Greatest Innovation Threatening Islam)?

Question : There is a book in the libraries called Lamadhhabiyah: The Most Dangerous Innovation in Islam. The questioner asks who says this title and how valid it is?

Answer : In reality, this title, Lamadhhabiyah: The Most Dangerous Innovation in Islam, implies that a person saying, "I do not follow a school of jurisprudence," is committing an innovation, and that it is the most dangerous innovation in Islam. This is the apparent meaning of the title. I have not read the book, but if the author’s intention in this book is what the title indicates, then it is wrong; it is wrong. The origin of the schools of jurisprudence is a later development after the era of the Companions (may Allah be pleased with them) and the era of the Tabi'un. So it is the following of schools that is the later development, not the absence of following schools. Unless the author intends by this description a specific person who denies everything written by the jurists of Islam and throws it into the trash; in that case, he has the right to describe their work as an innovation, because scholars still refer to the statements of previous scholars, verify them, and adorn them with the Book and the Sunnah. In any case, following the schools out of fanaticism without looking at the evidence is undoubtedly wrong, and it is not permissible. And no person of sound mind would say that one should follow everything he says and leave everything he leaves except the Messenger of Allah (peace and blessings be upon him). However, a person’s affiliation with a specific school, while striving to follow the evidence, is permissible. And thus are the scholars’ imams, as we mentioned earlier, such as Shaykh al-Islam Ibn Taymiyyah, who affiliated with specific schools, and yet they followed the truth wherever it was.
