Editorial Policy

Tool guides are written to explain the formula, show a worked example, and list common mistakes. Numbers in worked examples are checked with a calculation before publication.

Religious and health content is labelled as a general guide. For a ruling on Zakat or a diagnosis, consult a qualified scholar or health professional.

Each guide shows a last updated date. Sources are named where they are used, and we do not publish claims that we cannot support with a named source.

Each tool page shows a review status. Where subject expert review is pending, the page says so. We do not present a page as reviewed by a person until that review is complete and named.

Worked examples are calculated before they are published. Dates on each page show when the guide was last changed.
