Is the prohibition against delving into matters the Companions did not delve into limited to matters of the unseen?

The questioner : Shaykh, you mentioned that the women [asked] the Companions (may Allah be pleased with them) about the Prophet (peace and blessings be upon him). If the entire discourse is from the books of theology, are all the books of jurisprudence now from what the Prophet (peace and blessings be upon him) was asked about, and did the Companions have knowledge of them?

The Shaykh : You know the books of jurisprudence.

The questioner : For the sake of the question.

The Shaykh : I am asking you. If you do not know them, how can you ask about what you do not know?

The questioner : Welcome, exactly.

The Shaykh : And if you do know them, the books of jurisprudence consist of issues based on evidence. These are issues written by scholars, derived from the Book of Allah, the Sunnah of His Messenger, and the statements of the Companions. But what are the questions where one asks about matters of the unseen that involve no independent legal reasoning? I told you that matters of the unseen are those related to Allah, the Last Day, and the like, is that not so? As for matters of independent legal reasoning, ask. The mind has no right in matters of independent legal reasoning; we have mentioned and restricted this repeatedly.
