Beautiful Azan by Philippino

Adhan is called out by a muezzin from the mosque five times a day, traditionally from the minaret, summoning Muslims for mandatory (fard) worship (salat). A second call, known as iqama, (set up) then summons Muslims to line up for the beginning of the prayers. In the video below a man is trying to Say Adhan in same voice as it is given in Haram-e-Makkah

The main purpose behind the multiple loud pronouncements of adhan in every mosque is to make available to everyone an easily intelligible summary of Islamic belief. It is intended to bring to the mind of every believer and non-believer the substance of Islamic beliefs, or its spiritual ideology. In modern times, loudspeakers have been installed on minarets for this purpose.
