Being a country with the most Muslim population makes Indonesia a country with many mosques as places of worship. Which then gave rise to many Al-Qur'an Reading Gardens that stood in every mosque. One of the functions of the mosque is a means of education, both formal and non-formal. Since the time of the Prophet Muhammad, the mosque has not only functioned as a place of worship. The mosque functioned as a meeting room to gain knowledge and wisdom from the Prophet Muhammad. It is narrated that at the time of the Prophet Muhammad, the Prophet's Mosque, apart from being used as a place of worship, also functioned for the companions of the Prophet who did not have a place to live.
