Do Not Object to the Inheritance Laws Proposed by God
[4:33] For each of you, we have designated shares from the inheritance left by the parents and the relatives. Also those related to you through marriage, you shall give them their due share. GOD witnesses all things.
In the Quran God clearly spells out many of the instances where the women’s share is specifically specified while there is no indication of the male inheritor shares. This covers any of the inheritance that is left after the will of the deceased is fulfilled and all debts are paid off. People should not object to this.
