Following its conversion, the mosque became the property of the Sultan Selim Foundation, which was responsible for maintaining it. Other donors formed a number of foundations to help with the maintenance. Okçuzade Mehmed Paşa, a governor of Cyprus in the 16th century, donated a shop to provide income for the Sultan Selim Foundation; other donations include estates in the countryside and other shops. The foundation employed trustees ("mütevelli") to look after the funds and transferred 40,000 "akçe" annually to Medina in late 16th century. During the Ottoman period, it was the largest mosque in the whole island, and was used weekly by the Ottoman governor, administrators and elite for the Friday prayers. In the late 18th century, a large procession that consisted of the leading officials in the front on horseback, followed by lower-ranking officials on foot, came to the mosque every Friday.
