Fasting in Islam, (known as Sawm (صَوْم) or Siyām (صِيَام), also commonly known as Rūzeh or Rōzah (Persian: روزه‎)), is the practice of abstaining, usually from food, drink, smoking, and sexual activity. During the Islamic holy month of Ramadan Sawm is observed between dawn and sunset when the evening adhan is sounded.
