Ramadan (Arabic: رمضان Ramaḍān, Arabic pronunciation: [rɑmɑˈdˤɑːn]) (also Ramazan) is the ninth month of the Islamic calendar, which lasts 29 to 30 days. It is the Islamic month of fasting, in which participating Muslims refrain from eating and drinking during daylight hours and is intended to teach Muslims about patience, spirituality, humility and submissiveness to God. Muslims fast for the sake of God and to offer more prayer than usual.
Are you sure it's not called fisting? I'm just wondering because I've heard that it is quite common in foreign countries.
