The heirs are not permitted to dispose of other than their shares
Q: Your Eminence,
my mother, Hayaa bint Muhammad, died and left behind Muhammad, Turky and Turfah, the children of Zayd. Muhammad and Turky died and Turfah is still alive. Hayaa left behind a building rented for 8,000 Riyals. Do the children of Muhammad and Turky have shares in this sum of money or should it be left for Turfah to distribute it to the deserving inheritors?
Peace and mercy of Allah be upon you!
A:
Hayaa's estate should go to her legitimate inheritors after repaying her debts and executing her will. Each inheritor should take his share of inheritance. If any of her inheritors dies, his share should go to their inheritors. It is permissible for you to only use (Part No. 16; Page No. 434) your share of the inheritance of the house your mother Hayaa left behind. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
