Is it obligatory to divide a house inherited and registered in the mother's name among the heirs after the death of both parents, and how is this done according to Sharia, given that the mother willed to return the rights to her family?

It is not permissible to deprive an heir of their rightful share, for Allah Almighty has divided inheritances and determined the share for each heir. Whoever contravenes this has disobeyed Allah, transgressed His limits, and Allah has threatened them with the Fire.

If a man dies and leaves behind a wife, six daughters, and a brother's son, the inheritance is divided as follows: the wife gets one-eighth, the daughters get two-thirds, and the remainder goes to the brother's son.

If the house is divided into 24 equal parts, the wife gets 3 parts, the daughters get 16 parts, and the brother's son gets 5 parts.
