Who are the beneficiaries of the Islamic inheritance distribution?
In most cases, the inheritance goes to the son, daughter, husband, wife, parents, and in certain cases, grandparents, siblings, grandchildren, uncles, aunts, and so forth.
Is it Islamic to give everything to your spouse, assuming your spouse will distribute it fairly?
No, giving everything to the surviving spouse after death when there are other living beneficiaries is prohibited, since the Qur’an mandates other beneficiaries.
