Can opinions of other schools besides the Shafie school be used to help orphaned grandchildren who are blocked from inheriting from their grandfather?

Short answer

The Kelantan Council of Ulama ruled that the faraid rules are clear and fixed, with no disagreement among reputable scholars, so no new ruling on faraid is needed.

Summary

The Kelantan Council of Ulama ruled that the faraid rules are clear and fixed, with no disagreement among reputable scholars, so no new ruling on faraid is needed. Grandchildren whose father or mother died before the grandfather are blocked from inheriting. The problem can be addressed in two ways: the grandfather makes a bequest not exceeding one third of his estate or gives a reasonable gift during his lifetime, or the entitled heirs agree out of goodwill to give a portion of the inheritance to the grandchildren.

Written in our own words from the original fatwa — check the source before acting on it.

Oleh itu tidak timbul ketetapan faraid perlu difatwakan kerana apa yang terdapat dalam hukum adalah jelas dan tetap.
