Lists all available values for [TIMINGS]...

The below can be passed to [TIMINGS]...

  fajr      The dawn prayer time. Dependent on angle determined by authority (see salah authority)
  sunrise   Sunrise time. Fajr time ends at sunrise.
  dhuhr     The mid-day prayer time.

salah authority

Lists all the available calculation authorities to use with --auth <AUTH>

Usage: --auth <AUTH>

Explanation:
Calculation authorities are used for the calculation of Fajr and Isha.
The time for Fajr is described as dawn; when there is fine white line at the horizon.
Isha time is described as when the night sky has lost all the light from the sunset.
As this is quite ambiguous, the scholars have differed upon the angle that the sun
makes when these two times occur. Each authority has slightly different angles for
Fajr and Isha. Makkah uses a time difference from Maghrib (sunset).

The below can be used with the --auth <AUTH> option when calculating timings.

Authorities:
  MWL       Fajr at 18 degrees, Isha at 17 degrees. - Muslim World League
  ISNA      Fajr at 15 degrees, Isha at 18 degrees. - Islamic Society of North America
  Egypt     Fajr at 19.5 degrees, Isha at 17.5 degrees - Egyptian General Authority of Survey
  Makkah    Fajr at 18.5 degrees, Isha 90 min after Maghrib. - Umm al-Qura University, Makkah
  Karachi   Fajr at 18 degrees, Isha at 18 degrees. - University of Islamic Sciences, Karachi
  Tehran    Fajr at 17.7 degrees, Isha at 14 degrees. - Institute of Geophysics, University of Tehran
  Jafari    Fajr at 16 degrees, Isha at 14 degrees. - Shia Ithna Ashari, Leva Research Institute, Qum
