The importance of mosques in Islam is undeniable. Indeed, the mosque, or masjid as it is originally called, has been a religious and secular center since the early years of Islam, fulfilling a crucial function. Besides being a meeting place, headquarters, and administrative center for Muslims, it is also a place where people gather to worship collectively five times a day. Furthermore, Muslims have received education in these mosques on various subjects, primarily religious matters. The two most important aspects of mosques, in terms of their functions, are worship and education. During his lifetime, the Prophet Muhammad personally oversaw the education of Muslims, even assigning them special teachers. He did this in the mosque itself. He dedicated certain times of the day to the education of his companions, especially holding educational discussions with them after certain prayer times. Upon the request of women, he also held classes with them in the mosque on certain days of the week. In the section of the Masjid al-Nabawi called Suffa, he trained hundreds of students, some of whom even lived there. After the Prophet's death, the Rightly Guided Caliphs continued the mosque-centered way of life, and the Prophet's Sunnah was transmitted by some Companions through the establishment of narration circles in these mosques. The practice of education in the mosque, initiated by the Prophet, continued to be the center of hadith narration (education and teaching) for the Companions, the Tabi'un who followed them, and subsequent generations. Mosques, which were centers of education in general and hadith narration in particular, began to transfer this mission to madrasas from the 5th century AH (11th century AD) onwards.
