Ask about a transaction
Ask in ordinary words — about an instalment sale, a penalty for late payment, a rented shop, a pledge, a share in someone's business. What falls outside fiqh al-muamalat, such as worship, marriage or inheritance, Mizan leaves alone here: there is no corpus behind it. Inheritance shares are counted separately, in the calculator — that is arithmetic, not a ruling.
Mizan does not issue fatwas and does not replace a scholar. It is not legal advice and gives no contract force under the law of any country. Where the matter is serious, have the contract read by a specialist in Sharia and by a lawyer.
