The ruling on issuing fatwas based on the four schools of jurisprudence without knowing the evidence

Question:
Honorable Shaykh, may Allah grant you success.

Answer:
He says: If one acknowledges one of the schools of jurisprudence and issues a fatwa based on it without implementing it, is that permissible? Is it permissible to issue fatwas based on the four schools of jurisprudence if one knows the evidence? If one knows the evidence for the issue and the evidence for the opinion, then there is no harm. But without knowing the evidence, this is not permissible. One must search for its evidence and basis, and know that it is a correct and verified opinion; it is not taken at face value. Yes, it is necessary to rely on the evidence, search for its proof, and verify it. Yes.
