Islamic acts derive from the faith and law of Islam and include beliefs about God, forms of piety and expressions of faith (such as writing religious poetry, wearing a turban, or going on the pilgrimage to Mecca). Islamicate acts include anything not directly related to Islam as a faith, especially those inadvertent consequences of the Islamic requirements. Islamicate acts could be abandoned, even reversed, without doing damage to a believer's relations to God; nonetheless, they typify Muslim society. "Islamic literature" is religious writings; "Islamicate literature" is the entire output of Muslim communities, including even anti-religious works. "Islamic art" means art connected to holy subjects and "Islamicate art" encompasses all creations by Muslims. Turkish, which is spoken mostly by Muslims, is an Islamicate language; the arabesque is an Islamicate design; and the harem is an Islamicate institution. None of these follow directly from the faith or law of Islam, but all come with its civilization..
