Muslims throughout the world are observing the month of Ramazan, the holiest month in the Islamic calendar during which Muslims abstain from food and drink from dawn until dusk.

The world's nearly 1.8 billion Muslims began Ramazan on Wednesday, the holy month of dawn-to-dusk fasting and prayers. It is sacred to Muslims because tradition says the holy Quran was revealed to the Prophet Mohammad (pbuh) during that month.
