What does the Quran say about inheritance?
Allah prescribed inheritance shares in three key verses of Surah An-Nisa. These verses are among the most detailed legal rulings in the entire Quran, reflecting how seriously Islam takes the fair distribution of wealth after death.
“Allah instructs you concerning your children: for the male, what is equal to the share of two females. But if there are [only] daughters, two or more, for them is two-thirds of one's estate. And if there is only one, for her is half.”
— Surah An-Nisa 4:11
“And for you is half of what your wives leave if they have no child. But if they have a child, for you is one-fourth of what they leave.”
— Surah An-Nisa 4:12
The verse concludes with: “These are the limits set by Allah. Whoever obeys Allah and His Messenger will be admitted to Gardens under which rivers flow, abiding eternally therein. And that is the great success.” (Surah An-Nisa 4:13)
Frequently Asked Questions
What is Islamic inheritance (Mirath)?
Islamic inheritance law (Ilm al-Fara'id) is a system of wealth distribution prescribed by Allah in the Quran, primarily in Surah An-Nisa 4:11-12 and 4:176. The Prophet ﷺ said: "Learn the laws of inheritance and teach them, for they are half of knowledge" (Sunan Ibn Majah 2719). Shares are fixed by divine decree and cannot be altered by the deceased.
What are the shares prescribed in the Quran?
The Quran specifies six fixed fractions: 1/2, 1/4, 1/8, 2/3, 1/3, and 1/6. Each heir receives a share based on their relationship to the deceased. For example, a daughter alone inherits 1/2, while two or more daughters share 2/3. A husband inherits 1/4 when children exist, or 1/2 when there are none (Surah An-Nisa 4:11-12).
What happens when total shares exceed the estate?
When the sum of prescribed shares exceeds the total estate, a process called 'Awl (proportional reduction) is applied. Each heir's share is reduced proportionally so the total equals exactly 100% of the estate. This was first applied during the time of Umar ibn al-Khattab (may Allah be pleased with him) and is agreed upon by all four schools of jurisprudence.
Why does a son inherit double a daughter's share?
In Islamic law, a son's share reflects his financial obligations: he is required to provide for his wife, children, and aging parents. A daughter has no such mandatory financial burden — her inheritance is entirely her own. As Surah An-Nisa 4:11 states: "Allah instructs you concerning your children: for the male, what is equal to the share of two females."
Can a Muslim write a will (wasiyyah)?
Yes, but with limits. A Muslim may bequeath up to 1/3 of the estate to non-heirs or charitable causes (Sahih Bukhari 2742). The remaining 2/3 or more must be distributed according to the Quranic shares. A bequest to an existing heir is not valid unless the other heirs consent.
Should I rely only on this calculator?
This calculator handles common inheritance scenarios according to the Hanafi school. Complex cases involving missing heirs, disputed assets, debts, or bequests require consultation with a qualified Islamic scholar or Mufti. The Prophet ﷺ emphasized learning inheritance law precisely because of its complexity.
