Is Zakah due on the worker's (Mudarib's) share of profit in Mudarabah?

Primary text

The worker (Mudarib) does not owe Zakah on his share of the profit until the division of assets occurs, and then a new Hawl must commence from that point. This is because the worker's ownership is not yet complete; the profit is contingent upon the principal surviving, meaning the worker cannot exclusively claim or dispose of it freely. This differs from lost or usurped property where ownership is established but possession is temporarily withheld.
