Where the four schools differ
This question turns on one issue in our madhhab register: A discretionary trust interest — is anything owned? — whether a person who is only a potential object of a trustee’s discretion, with no vested interest, owns anything that enters his estate when he dies
Researched positions from our madhhab register — issue discretionary-trust-vested-share, reviewed 2026-09-01.
What is actually owned, and what nobody has ruled. The classical test is milk, and the definitions are precise about what it consists of. Al-Qarafi: ownership is a ruling of the law, assessed in a thing or in its use, which produces the enablement of the person it attaches to to take the benefit of the thing and to take a price for it. Ibn al-Shat says the same in plainer words: to be enabled by the law, in person or through an agent, to use the thing and to take a counter-value. Ibn Taymiyya then gives the mark of the complete kind: the owner can dispose of the corpus by sale and by gift, “and it is inherited from him”, and can dispose of its uses by lending and letting. What falls short of that the jurists call defective or, in al-Zarkashi’s word, weak ownership; and they separate again between ownership that is settled and ownership that can still fall away. The recognised causes of ownership are a closed list — transfer by contract, succession on death, and original acquisition by taking a thing that belongs to nobody. A hope that a trustee may exercise a discretion is none of these. Measured against al-Qarafi’s definition it produces no enablement at all: the person cannot use the fund, cannot sell his hope, cannot be paid for it, and cannot pass it on — which is Ibn Taymiyya’s test failing at the very point that matters here. The gap, stated plainly. That reasoning is ours, not a ruling, and the register will not dress it up as one. We searched for a determination on the common-law trust from a recognised body and found none. AAOIFI, revising its Waqf standard in 2019, identified the “financial trust”, said it resembles waqf in some respects, and expressly excluded it from the standard’s scope. The International Islamic Fiqh Academy’s official compilation of every resolution to 2021 — 641 pages — contains nothing on the Anglo-American trust; every use of “trust” or “trustee” in it is about amana in a mudaraba, in zakat administration or in sukuk. So there is no ruling to report, and a family with a discretionary trust in the picture needs the specific trust deed read by someone competent in both laws, rather than a general answer this register does not have.
