If your father predeceases you and he does not have both or one of his
parents and his wife, then his estate will be divided into 20 equal shares
and distributed as follows: Daughter receives 10 shares; Each brother
receives 2 shares; and each Sister receives 1 share.
If your father is survived by his parents or his wife, then the ruling will
and Allah Ta’ala Knows Best
Mufti Ebrahim Desai
