The ordinary adhan consists of: Allahu akbar (4 times); the first testimony (2); the second testimony (2); hayya ‘ala al-salah (2); hayya ‘ala al-falah (2); Allahu akbar (2); la ilaha illa Allah (1).
This gives 15 verbal units in the Hanafi formula without tarjī‘. A distinct additional phrase is included for Fajr.
