Effect on agency when the appointed Muslim agent apostatizes (Irtidad)?

Primary text

If a Muslim agent apostatizes, the agency contract does not become void, regardless of whether the apostate joins the Abode of War (Dar al-Harb) or remains residing in the Muslim territory. The evidence supporting this is that the agent remains capable of transacting for their own benefit, similar to a case where they did not join Dar al-Harb. Furthermore, since apostasy does not invalidate the *initiation* of the agency, it should not invalidate its continuation, analogous to other forms of disbelief.
