How can a vow made by a grandfather be fulfilled, where he bequeathed the holding or attendance of a Mawlid and the recitation of a portion of the Holy Quran in exchange for a piece of land, given that both beneficiaries have passed away and their children are dispersed?

It is permissible to agree with a reciter to recite a portion (juz') or a surah (definition) daily for a fee, knowing that there is a scholarly disagreement regarding the permissibility of taking a fee merely for reciting the Qur'an. The questioner shares with his brothers and cousins the responsibility of preserving the bequeathed property and spending its proceeds as specified. If they do this on his behalf, it suffices. If there is fear of the bequest being lost, they must place it under the judge's supervision so he may appoint an overseer for it. If the questioner's father and uncle had appointed someone to act on their behalf concerning the bequest, that person is the sole executor. The questioner has the right to demand his share of the proceeds from the shared land, and he may donate what has passed. A bequest is not permissible for more than one-third of the deceased's wealth, and anything exceeding one-third is not enforceable except with the heirs' permission.
