Who may be appointed wasi (executor and guardian)

All four schools want the same qualities in a wasi — adulthood and legal capacity, Islam, integrity and the ability to do the job. They differ on what failing one of them does. Three schools treat them as conditions of validity, so an appointment that fails one is void. The Hanafi school treats the appointment as valid and puts the remedy in the judge’s hands.

Where the four schools differ

This question turns on one issue in our madhhab register: Who may be appointed wasi (executor and guardian) — what does a person have to be, for a Muslim’s appointment of them as wasi to hold good?

They are conditions of validity. The wasi must be of age and of sound mind, Muslim, and of established integrity (‘adala — in the Maliki formulation, trustworthiness and the competent handling of a child’s property). An appointment that fails one of these does not take effect at all: a Muslim cannot validly appoint a non-Muslim over his children or his estate, and Ibn Qudama records Malik and al-Shafi’i, with one of the two reports from Ahmad, as holding the same of a person of doubtful integrity. The Shafi’i list adds that the wasi be free, not an enemy of the person in his charge, and not of unknown character; a blind man may serve. The Maliki school adds that a wasi who later loses a qualification — who apostatises, or becomes incapable — is removed.

Hanafi

The appointment stands; the judge fixes it. Where the person named is a minor, a non-Muslim, or of doubtful integrity, the appointment is valid and anything he does before he is removed takes effect — but the judge must replace him with someone qualified, substituting a Muslim for a non-Muslim, and removing a person of doubtful integrity only where he is actually suspected with the money. A wasi who meets every condition may not be removed by the judge at all, because he stands in the place of the deceased who chose him. Ibn Qudama states that a Muslim’s appointment of a non-Muslim is invalid with no disagreement he knows of; al-Jaziri records this Hanafi rule expressly, so the attribution of unanimity is not one we can pass on.

Why this one matters in Canada

For a Canadian Muslim the practical bite of this is narrow but real. Naming a non-Muslim executor — a trust company, a professional trustee, a spouse who has not converted — is a live question, and three of the four schools treat such an appointment as ineffective in itself. That is a fiqh conclusion, not an Ontario one: provincial law will appoint whoever the will names. Families who care about the point usually solve it by naming a qualified person and letting them retain professional help, which no school objects to.

Which row is yours? Most families follow the school of their region of origin — the four madhahib page maps them. The comparison is here so you can see your school’s position, not so you can pick the convenient answer — assembling a plan from several schools at once (talfiq) can produce a distribution no school would accept. If your estate turns on this point, put it to a scholar of your school.
