If a man delegates authority to someone to issue Talaaq to his wife at any time in the future on the demand of the wife, can the husband cancel this r

Answer

When the right of issuing Talaaq is given by tafweedh (delegating authority), it cannot be cancelled. The person will enjoy the right to issue Talaaq for as long as he/she has not issued Talaaq. On the other hand, the husband can cancel taukeel (appointing an agent to issue Talaaq) at any time. He can terminate the wikaalat (agency).
