Direct answer
How much does a grandmother inherit in Islam?
A grandmother (maternal or paternal) inherits a fixed 1/6, established by the Sunnah. The maternal grandmother is blocked by the mother; the paternal grandmother is blocked by the mother and by the father. Multiple eligible grandmothers share the single 1/6.
A grandmother (maternal or paternal) inherits a fixed 1/6, established by the Sunnah. The maternal grandmother is blocked by the mother; the paternal grandmother is blocked by the mother and by the father. Multiple eligible grandmothers share the single 1/6.
- Mother is alive → Blocked
- No mother (and for paternal side, no father) → 1/6
- 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 Grandmother's Quranic Share by Situation
The basis is Sunnah (Hadith on the grandmother's sixth). The share depends on which other heirs survive the deceased:
| Situation | Share | Note |
|---|---|---|
| Mother is alive | Blocked | The mother excludes the grandmother(s). |
| No mother (and for paternal side, no father) | 1/6 | The sixth, shared if more than one grandmother qualifies. |
When the Share Changes or Is Blocked
A maternal grandmother is blocked by the mother. A paternal grandmother is blocked by both the mother and the father. When more than one grandmother is eligible, they divide the single 1/6 equally — it is not 1/6 each.
Example: a person dies leaving a husband, a maternal grandmother, and a son (no mother)
The husband takes 1/4 (a child exists), the grandmother takes 1/6, and the son takes the remaining residue. Had the deceased's mother been alive, she would have taken the 1/6 and the grandmother would inherit nothing.

Why U.S. Law Won't Deliver This Share
U.S. intestacy rarely reaches a grandparent when closer heirs exist, so the grandmother's Sunnah-established 1/6 is lost without an explicit Islamic will directing it.
An Islamic will is the only way to make sure the grandmother'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.
