Granddaughter (son's daughter)'s Share of Inheritance in Islam: 1/2, 2/3, or 1/6 to complete two-thirds
A son's daughter inherits much like a daughter when there is no direct daughter: 1/2 (one) or 2/3 (two or more). With exactly one direct daughter present, the son's daughter takes 1/6 to complete the two-thirds. She is blocked by a son, or by two or more daughters unless a male relative at her level revives her.

Direct answer
How much does a granddaughter (son's daughter) inherit in Islam?
A son's daughter inherits much like a daughter when there is no direct daughter: 1/2 (one) or 2/3 (two or more). With exactly one direct daughter present, the son's daughter takes 1/6 to complete the two-thirds. She is blocked by a son, or by two or more daughters unless a male relative at her level revives her.

- No daughter or son; one son's daughter → 1/2
- No daughter or son; two or more son's daughters → 2/3 (shared)
- Exactly one direct daughter present → 1/6
- Deceased left a son, or two+ daughters (no equal-level male) → Blocked
- Combined heirs trigger blocking, ʿawl, and radd — use the Faraid calculator
- U.S. intestacy does not produce these shares — an Islamic will is required
The Granddaughter (son's daughter)'s Quranic Share by Situation
The basis is Surah An-Nisa 4:11 (by analogy). The share depends on which other heirs survive the deceased:
| Situation | Share | Note |
|---|---|---|
| No daughter or son; one son's daughter | 1/2 | Like a single daughter. |
| No daughter or son; two or more son's daughters | 2/3 (shared) | Like multiple daughters. |
| Exactly one direct daughter present | 1/6 | Completes the collective two-thirds for the female descendants. |
| Deceased left a son, or two+ daughters (no equal-level male) | Blocked | Excluded unless a son's son at her level makes her a residuary. |
When the Share Changes or Is Blocked
A son's daughter is blocked by a son of the deceased and, generally, by two or more direct daughters — unless a son's son at her own level pulls her in as a residuary (taʿsib). A single direct daughter does not block her but caps her at the 1/6 'completion' share.
Example: a man dies leaving one daughter and one son's daughter (no sons)
The direct daughter takes 1/2. The son's daughter takes 1/6, completing the two-thirds collective share for the female descendants (1/2 + 1/6 = 2/3). The remainder passes to other residuary heirs (e.g. the father or brothers), or returns by radd if none exist.

Why U.S. Law Won't Deliver This Share
These 'completion' and blocking rules have no analogue in U.S. probate. A son's daughter's right — including her 1/6 alongside a single aunt-level daughter — is only secured through an Islamic will and an accurate Faraid calculation.
An Islamic will is the only way to make sure the granddaughter (son's daughter)'s Quranic share is honored instead of your state's default intestacy rules. ShariaWiz builds scholar-reviewed, state-specific Islamic wills and trusts — an Islamic will from $199, with a built-in Faraid engine.

The Final Step: Your Scholar Conversation
Major Islamic inheritance (Faraid) decisions involve nuances that vary by scholarly opinion and personal circumstance — which is why HalalWallet is built as the research step, not the ruling. We do the homework on comparisons, structures, and oversight; a qualified Islamic scholar, your local imam, or a Shariah-certified financial advisor covers what no comparison site can — guidance specific to your situation. Bring your shortlist to that conversation so it starts at the decision, not the basics.
How to use this comparison: HalalWallet is an independent educational comparison platform — by design, we do not provide financial, legal, or religious advice. We do the research homework so your final checks are quick and personal.
Product structures and Shariah oversight vary by provider, so finish with three built-in steps:
- Confirm current terms and halal compliance directly with the provider — their quote is final.
- Review the contract structure (Murabaha, Ijara, Musharakah, etc.) and any disclosed Shariah board opinions.
- Bring your shortlist to a qualified Islamic finance advisor or scholar, so the conversation is about your situation, not the basics.
