Do the four dwellings mentioned in the question—one in the name of the deceased and three in the names of three of his heirs—count as part of the inheritance, entitling the mother of the four sons who did not inherit dwellings to share in them, or is their right restricted to the large dwelling only, taking into consideration that there was a zakat debt owed by the deceased that he did not pay, and his anger towards one of his sons?

The heirs must pay zakat from the inheritance before its distribution. The deceased's wife receives one-eighth due to the presence of a lineal descendant, and the remainder goes to the seven sons by ta'sib (agnatic inheritance), with the male receiving the share of two females. The wealth is divided into eight shares. The disobedient son inherits and is not deprived of the inheritance; he must repent, as disobedience to parents is a major sin. Filial piety after the parents' death is achieved by supplicating for them, seeking forgiveness for them, fulfilling their pledges, honoring their friends, maintaining kinship ties related to them, and giving charity on their behalf. Regarding the houses the father bought for his sons: if he gifted them to them during his lifetime, not during his death illness, and they took possession of them, then it is a valid gift, and the other heirs have no right to them, provided there was justice in the gift among all the children. Matters of inheritance are serious and must be referred to the Sharia courts for investigation.
