SalahLib — a multi-language library for Islamic prayer times.

Provenance
==========

This library is implemented from permissively-licensed and factual sources:

  * PrayTimes v3 (MIT, © 2007–2025 Hamid Zarrabi-Zadeh) — the core kernel mathematics.
  * USNO "Sun Approx" solar-position reference (public domain — US federal government work).
  * The published prayer-time calculation method data (factual depression angles / minutes).
  * Moonsighting seasonal-twilight coefficients, via the MIT-licensed `adhan` library.
  * The AlAdhan Prayer Times API (https://aladhan.com) — used as a black-box reference to validate accuracy
    and to derive each AlAdhan-specific behaviour (see SPEC §12–§13).

Acknowledgements
================

We thank and acknowledge:

  * Hamid Zarrabi-Zadeh and PrayTimes.org (https://praytimes.org), for the original algorithm and its
    MIT-licensed v3 release on which the kernel is based.
  * The Islamic Network (https://islamic.network), for the prayer-times ecosystem and the public AlAdhan API
    that made independent verification possible.
  * The US Naval Observatory, for the published "Sun Approx" solar-position reference.
  * Batoul Apps, for the MIT-licensed `adhan` library.
