What happens to the estate of a person who dies and has absolutely no heirs?

Answer

His estate will be given to the Fuqara (poor Muslims). If he has poor relatives who are not heirs, they have a prior right. Non-inheriting relatives are stepmothers, step children, wife's / husband's relatives, Ridhaai' (Milk) brothers/ sisters, adopted children, etc. There are no fixed shares in this case. The executor should distribute according to his discretion.
