Does asking about the soul fall under the category of knowledge that is of no benefit?

Al-'Uwaishah: Our Shaykh, on the occasion of the assumptions and possibilities you mentioned, it reminded me of a question. That is, is the one who asks about the existence of a soul or its non-existence in the same category as this knowledge that is of no benefit? The one who asks about the state of existence, they say, "Is there growth for the soul or not?" Is this in the same category, the category of, meaning, unbeneficial knowledge?

The Shaykh : That is correct.
