The Fajr Adhan in Ja'fari practice

Fajr is called at dawn, before sunrise. Because dawn is gradual rather than instantaneous, the time it is called depends on the calculation convention in use as well as the local horizon.

The Ja'fari Fajr call follows the same sequence as the other prayers. The phrase 'al-salatu khayrun min al-nawm', included in the Fajr Adhan in major Sunni schools, is not treated as part of the call in Ja'fari practice.

You will see 'subh' and 'fajr' used for the same prayer in different sources, and 'fajr sadiq' used specifically for true dawn as distinct from the earlier false dawn.

At high latitudes the interval between dawn and sunrise compresses or stretches dramatically through the year, which is why two Fajr timetables for the same city can differ by more than people expect.
