Wednesday marked the first day of Ramadan. During this month, observing Muslims around the world fast by abstaining from food and drink from sunrise to sunset. Fasting in Ramadan is one of the five pillars of Islamic faith along with belief in the oneness of God and in Muhammad as God's messenger, performing the daily prayers, paying the yearly charity due (Zakat), and performing the pilgrimage to Mecca (Hajj).
The command for fasting came from God to Prophet Muhammad the second year in the Islamic calendar, 624 AD.
"Ramadan is the month in which was sent down the Quran, as a guide to mankind, also clear signs for guidance and judgment between right and wrong. So every one of you who is present at his home during that month should spend it in fasting. But if anyone is ill, or on a journey, the prescribed period should be made up by days later. God intends every facility for you; He does not want to put you to difficulties. He wants you to complete the prescribed period, and to glorify your Lord. In that God has guided you; and perchance you shall be grateful."(Al-Quran, 2:183)
