Where the four schools differ
This question turns on one issue in our madhhab register: Which marriages let a spouse inherit — which marriages create a right to inherit as a spouse, and does a marriage contracted in a final illness count?
Researched positions from our madhhab register — issue nikah-validity-inheritance, reviewed 2026-09-01.
What has to be true of the marriage itself. All four schools form the contract by offer and acceptance — the Kuwaiti Mawsu’a, entry Nikah §46, records that as agreed. They part company on the rest. On the wali (§66): the Maliki and Shafi’i schools make him a pillar of the contract, so that there is no valid marriage without one; the Hanbali school makes him a condition of validity, al-Mardawi calling that “the school, and the companions are upon it”; the Hanafi school treats guardianship over an adult woman of sound mind as a matter of recommendation, so she may contract for herself. On witnesses (§116): the Hanafi, Shafi’i and Hanbali schools require two, the Shafi’is as a pillar and the other two as a condition; the Maliki school makes witnessing at the contract recommended but requires it at consummation, and refuses to uphold a marriage the parties meant to keep secret. On the mahr (entry Mahr §3): it is owed in every marriage, but naming it in the contract is not a condition of validity — the encyclopaedia says that is so “by the agreement of the jurists”, and cites a work of each school for it. These matter here because they are what decides whether a given marriage is sahih or fasid — and, on the Maliki rule above, a defect the schools argue about is not the same as one they all accept.
