Does the rental benefit accrue to all heirs, or only to the one who works in it, with the obligation for the one who works in it to reconcile with the remaining heirs regarding their right?

The lease contract is not terminated by the death of the lessee, according to the majority of scholars. The heirs are entitled to benefit from the leased property. If they waive their right or reach a settlement, there is no harm. Otherwise, each heir benefits from the usufruct in proportion to their inheritance, because benefits are inherited just like physical assets. This applies if the deceased left an estate. However, if the deceased did not leave an estate, the heirs are not compelled to pay the rent and utilize the benefit.
