Can the buyer fulfill the seller's right to usufruct by providing an equivalent benefit from another object?

Primary text
The buyer is not obliged to accept payment in lieu of the stipulated usufruct or an offer to provide an equivalent benefit from a different object; the buyer retains the right to demand the usufruct from the object itself. This is affirmed by Ahmad because the seller's right is attached specifically to that item, akin to a lessee who is offered an equivalent property instead of the rented one. Furthermore, the seller may have a specific interest in utilizing the benefits of that exact object, thus preventing compulsion to accept monetary compensation.

If both parties mutually agree to substitute the usufruct with compensation or an equivalent benefit, the arrangement is permissible because the right belongs to both contracting parties, and they have the discretion to modify it.
