Hawzah News Agency – Is it permissible for someone to stipulate in their will that half of their estate be spent on holding a memorial service for them after they have passed away?

A: There is no objection to providing for one’s funeral as there is no ceiling to that. However, the provision in the will of the deceased is enforceable in only one third of the entire estate. Any amount over and above the one-third share should be subject to the consent and permission of the heirs.
