How is the inheritance calculated for a male who died leaving behind: (1) a full brother, (2) two daughters, and (3) three full sisters, taking into account that the deceased had Alzheimer's for more than 30 years and did not pay a deferred dower to his divorced wife, who had collected money for him from their son's compensation, in addition to the presence of heirs in a house?

The share of the two daughters is two-thirds, based on the Hadith of the Prophet, peace and blessings be upon him, and the consensus of scholars. The remainder is divided among the full brother and full sisters by ta’seeb (agnatic inheritance), with the male receiving the share of two females.

The inheritance is divided into 15 shares: 10 shares for the two daughters (5 shares for each), two shares for the full brother, and one share for each full sister.

The deferred dowry (mahr mu'akhkhar) becomes due to the wife upon the arrival of its agreed-upon term. If no term was specified, it becomes due upon separation (by death or divorce). If the deceased did not pay the due deferred dowry, it is considered a debt that must be taken from the estate before its distribution.

Everything proven to be owned by the deceased is considered part of his estate. Whoever knows about any such asset must inform the heirs so it can be added to the estate.
