Ramadan is the ninth month of the Islamic calendar; Muslims worldwide observe this as a month of fasting. This annual observance is regarded as one of the Five Pillars of Islam. The month lasts 29–30 days based on the visual sightings of the crescent moon, according to numerous biographical accounts compiled in hadiths. The word Ramadan comes from the Arabic root ramida or ar-ramad, which means scorching heat or dryness.
While fasting from dawn until sunset Muslims refrain from consuming food, drinking liquids and sexual relations. According to Islam, the sawab (rewards) of fasting are many, but in this month they are believed to be multiplied. Fasting for Muslims during Ramadan typically includes the increased offering of salat (prayers) and recitation of the Quran.
