An Islamic estate, divided and explained line by line.

Why you can rely on it

The engine is tested against 65 solved cases from the standard works: Ibn Abi Zayd's Risala, Khalil's Mukhtasar, the Rahbiyya, al-Mughni, the Sirajiyya. They run again on every code change, and you can read every one of them.

Nothing leaves your phone

The whole calculation runs in your browser. No account, no server, no database. A share link carries the case itself after the # sign, the part of an address browsers never send to a server.

Once the page has loaded, Mirath also works without a connection.

What it handles

• Spouses (up to four wives), parents, grandparents, children and sons' children
• Full, paternal and maternal siblings, nephews, paternal uncles and cousins
• Fixed shares, residuaries ('asaba), full and partial exclusion
• 'Awl, radd, al-'Umariyyatan, al-Mushtaraka, al-Akdariyya, al-Malikiyya
• The grandfather with siblings (Zayd's division, al-Mu'adda)
• Funeral costs, debts, and a bequest capped at one third

What it doesn't do yet

• A missing person (mafqud) or an unborn child (haml)
• The intersex heir (khuntha)
• Simultaneous deaths (drowning, accidents)
• Relatives through women (dhawu al-arham), beyond flagging them
• Impediments (homicide, difference of religion): none are assumed

In those situations, go straight to a notary or a scholar.
