He bequeathed to his wife the residence of a villa, which then reverts to the heirs after his death

Question: His Eminence, our beloved father, Shaykh 'Abd al-'Aziz ibn 'Abd Allah ibn Baz (may Allah preserve him)
Peace be upon you, and Allah's mercy and blessings.
I have relinquished the rent for the residence of the villa that is my property and located in the old al-Shifa district of Muhammad ibn Turkay to my wife for the duration of her life. No one has the right to displace her or evict her, and after her death, the villa reverts to the heirs as is customary. Please issue a ruling for us, may Allah guide you and protect you with His care.

Answer: And upon you be peace, and Allah’s mercy and blessings, after that:
No one may bequeath anything to any of the heirs; because of the saying of the Prophet (peace and blessings be upon him): . By this, you know that the aforementioned bequest is not valid except with the permission of the heirs who are being benefited. If they allow her to reside in the villa after your death, their right is waived, and the right of those not being benefited remains, as well as the right of any of the benefited heirs who did not give permission.
May Allah guide everyone. And peace be upon you and the mercy of Allah and His blessings.
