Ramadan, the Islamic month of fasting, began earlier this week, with the observation of the Hilal, or new moon. Throughout this ninth month on the Islamic calendar, devout Muslims must abstain from food, drink, and sex from dawn until sunset. The fast, one of the five pillars of Islam, is seen as a time for spiritual reflection, prayers, and charity. After sunset, Muslims traditionally break the fast by eating three dates, performing the Maghrib prayer, and sitting down to Iftar, the main evening meal, where communities and families gather together. Gathered here are images of Muslims around the world observing Ramadan this year.
