What Wifaq calculates, how, and what it refuses to settle. Within the law of France. Updated: June 2026.
This fingerprint is recomputed in your browser, from the file actually served. Any change to the engine changes the fingerprint: you, or a scholar, can thus verify that you are looking at one precise, frozen version.
Wifaq displays, side by side, what the law of France provides and the Islamic distribution of an estate (farā'iḍ), as a matter of knowledge. The calculation is done in exact fractions; the amounts in euros are only an illustration. Everything happens in your browser: no data reaches us.
Wifaq gives neither a religious ruling (fatwa), nor personalised legal advice, nor any deed. When the schools differ, the platform shows it and refers you to a scholar; when a case falls outside its scope, it says so rather than guessing.
Fixed shares (furūḍ), residuary heirs (ʿaṣaba, including the ʿaṣaba maʿa-l-ghayr), exclusion of an heir by a nearer one (ḥajb), proportional reduction when the shares exceed unity (ʿawl), redistribution of the remainder (radd), the concurrence of the grandfather and the siblings (jadd wa-l-ikhwa: muqāsama and the « best of three »), and the classic named cases: ʿUmariyyatān (Gharrāwayn), Akdariyya, and the Himāriyya (where the schools differ, see below).
The school selector covers the four Sunni schools, with the Mālikī school by default (« or I don't know »). The divergences explicitly encoded in the sealed engine (the one covered by the fingerprint above) concern, among others: the exclusion of the siblings by the grandfather among the Ḥanafīs, the restriction of the Akdariyya, and the mushtaraka (al-ḥimāriyya), flagged as an unsettled divergence. Wherever a position depends on the school and affects your case, the tool displays « to be validated with a scholar ».
Separately: preparing the will template also adjusts the treatment of an unperformed hajj according to your school (a deductible debt among the Shāfiʿīs and Ḥanbalīs, charged to the third among the Ḥanafīs and Mālikīs). This logic belongs to drafting the document, outside the sealed calculation engine, and is therefore not covered by the fingerprint.
Matrimonial regime (seven regimes, with prior liquidation of the community), orders of heirs, representation of branches, forced-heirship reserve and disposable portion, the spouse's option (a quarter in full ownership or the usufruct of the whole, valued under the scale of article 669 of the tax code), concurrence of parents and siblings (article 738), the spouse's reserve in the absence of descendants (article 914-1).
A warning layer flags the situations where a foreign law may intervene (habitual residence outside France, distinct from tax residence; foreign or dual nationality; real estate abroad), together with a reminder of the compensatory levy (article 913 paragraph 3, law of 24 August 2021).
The engine is continuously tested by 48 automated checks whose expected result is known and fixed: any change to the engine must leave them green. Here are the scenarios covered (current version):
The rules of the farā'iḍ distribution follow the classical positions of the four Sunni schools. The French devolution follows the Civil Code (reserve and disposable portion: articles 912 to 917; the spouse's option: articles 757 and 758; representation: articles 751 and following; usufruct scale: article 669 of the tax code; concurrence of parents and siblings: article 738; the spouse's reserve: article 914-1).
An unstable text is flagged as such: the compensatory levy (article 913 paragraph 3, law of 24 August 2021) is the subject of discussion as to its conformity with European Union law. Our calculations and our warnings are dated and may evolve with the law.
A religious and legal committee is being formed to validate and develop these rules. Until its members are publicly named, what precedes commits the Wifaq team alone, and every decision must be validated with a notaire and, when your situation calls for it, with a qualified scholar.
