"A trust, do not do such and such": Is this an oath by a created thing?

Question:
He says: Honorable Shaykh, may Allah grant you success, if someone says, "A trust, do not do such and such," is this an oath by a created thing?

Answer:
No, that is not it. The prohibition against swearing by a trust has come in an explicit text. So if he intends to swear an oath, then this is not permissible. But if he does not intend to swear an oath, and is only saying, "This is a trust with you, this is a secret, a trust with you, do not disclose it," then that is something else; it is not an oath. Yes.
