Is it necessary to disburse one-third of the rental income from real estate, accrued after death, and include it within the bequeathed one-third, or does all the rent belong to the heirs, given that the properties have passed to them?

A will made by the deceased can either be for a specific amount, which is then disbursed from the estate before its distribution, provided it is one-third or less, and the legatee is not entitled to more than what the deceased specified. Or it can be for an undivided share of the estate, in which case the legatee receives a share like all other shares of the estate and is considered a partner in all the estate's assets and any growth or loss that occurs to them. The legatee's right in this case is established in all the assets, and they have a share of the rental income from properties as long as the estate has not been divided. It should be noted that matters of inheritance are serious and complex, and they should be referred to the Sharia courts for investigation.
