Can a husband revoke his permission for his wife to perform voluntary Hajj after granting it but before she enters Ihram?

Primary text
If he grants permission, he retains the right to revoke it unless she has already entered the state of Ihram. If she enters Ihram or he grants permission, he cannot revoke it or force her out of it, as it becomes binding upon commencement, treating it like an original obligation.

If he revokes his permission before her entry into Ihram, the situation is treated as if he never gave permission.
