Is something a person bought with money he took without the owner's permission, then fully returned the money, considered unlawful and impermissible to benefit from?

The treasurer and other employees are entrusted with the funds in their possession, and they must preserve and take care of them, for Allah Almighty says: "Indeed, Allah commands you to render trusts to whom they are due." It is not permissible for them to dispose of these funds in any way other than what they have been commanded, and it is a betrayal for the treasurer to borrow from the funds under his hand for himself. Therefore, what was taken from the fund must be returned immediately.
