What is the ruling of Sharia regarding a man writing over all of his possessions - which consist of a house - to a daughter he sponsored, raised, and married off, after his wife's insistence and with her help in writing an initial sale contract for the house, thereby disinheriting his heirs, who are two full brothers and two full sisters? Do they have the right to claim the inheritance?

The inheritance is to be divided among full siblings, male and female, by 'asaba (agnatic succession), with the male receiving the share of two females, after settling debts and executing wills. As for disputes and disagreements, their reference point is the Sharia (definition) judiciary, not the fatwa (definition), and it is forbidden to cause discord between the testator and his heirs. Furthermore, inheritance cases must be referred to the Sharia courts for investigation, as they are serious and complex issues that require research and scrutiny.
