The adzan version in question is the difference between one muezzin and another in terms of sound color, sound style, the influence of local customs or culture, and so on.
Adhan is a medium to echo the unity of Allah and the message of the Prophet Muhammad. In addition, the Adhan is also used as a call for Muslims to inform the time of entry of the Fardhu prayer which is the five rak'ah prayer. The unique fact about the call to prayer is that the call to prayer does not stop ringing. This is due to the time difference in each country. The religion of Islam has spread all over the world, including Indonesia, therefore, the call to prayer is echoed in various versions.
