How Faraid.AI calculates — and how the AI is kept honest

1. A deterministic engine computes the shares — not the AI

Every share is produced by a rule-based algorithm that encodes classical Sunni inheritance (faraid) — fixed shares (furūḍ), residuary (ʿaṣaba), blocking (ḥajb), ʿawl and radd — across the four Sunni schools (Hanafī, Shāfiʿī, Mālikī, Hanbalī). The AI never invents shares; it only explains the numbers the engine already produced.

2. The AI's job: explain, cite, flag — within scope

• Explains each heir's share with the relevant Qur'anic verse / hadith / classical text.
• Answers only inheritance/will/estate questions; off-topic requests are politely declined.
• Flags inconsistencies or missing inputs — it does not assert "the calculation is correct".
• Cites real sources (Nisāʾ 11/12/176, al-Sirājiyya, al-Mabsūṭ, al-Mughnī, Bidāyat al-Mujtahid) — never "a database/PDF".

3. Sources

Qur'an (Sūrat al-Nisāʾ 11, 12, 176); authenticated hadith on inheritance and the killer's exclusion; and the classical fiqh corpus — al-Sirājiyya, al-Sarakhsī's al-Mabsūṭ, Ibn Qudāma's al-Mughnī, Ibn Rushd's Bidāyat al-Mujtahid. The retrieval layer surfaces these passages to the AI as grounding; outputs are checked against a golden-case test set with citations.

4. Limits — please read

• This is a decision-support and educational tool, not a fatwa, court ruling or notarial deed.
• National Law mode for some countries is marked v1 / experimental: certain country-specific provisions are noted but not yet computed.
• Civil-law formalities, taxes and document validity vary by country and must be reviewed by a qualified local lawyer / scholar before signing.
• Results depend on the accuracy of your inputs.
