Central Mosque. In the event of a religious holidays like Eid al-Fitr, for example in Indonesia, where the Kalimah (speech) has to be recited out loud all day long, mosque operators uses this recording method to create a looping recital of the Kalimah. The muezzin is chosen for his ability in reciting the Adhan clearly, melodically, and loudly enough for all people to hear.

During the Friday prayer (Salat al-Jumu'ah), there is one adhan but some Sunni Muslims increase it to two adhans; the first is to call the people to the mosque, the second is said before the Imam begins the khutbah (sermon). Just before the prayers start, someone amongst the praying people recites the iqama as in all prayers. The basis for this is that at the time of the Caliph Uthman he ordered two adhans to be made, the first of which was to be made in the marketplace to inform the people that the Friday
