Can the Hissa Jaidad obligation on a business be fulfilled during the Musi's lifetime?

Yes, but if the business grows in value after the assessment and payment, the Musi remains responsible for paying Hissa Jaidad on the increase in net worth.

An increase may result from reinvestment of profit (on which Hissa Amad was already paid) or additional capital. The same principle applies as with a house extension built from savings — the newly created asset gives rise to a fresh Hissa Jaidad obligation.
