Is machinery used for construction included as property in Wasiyyat?

In any kind of business, only the portion that belongs to the Musi is considered their property. The total value of all assets minus amounts owed to creditors equals the Musi's portion on which Hissa Jaidad is paid.

Hissa Jaidad on businesses is required to be paid after the Musi's death. If the Musi wishes to pay during their lifetime, a Tashkhees (assessment) is made of the total value of the business, all amounts owed are subtracted, and Hissa Jaidad is payable on the remainder.
