Thursday, June 18, 2015 marks the start of the holy month of Ramadan. Today, Muslims all over the world are observing the fast during Ramadan but fasting is not invented by Muslims but is an age old tradition observed by other religions as well.
Fasting is mentioned in the Bible, the Old Testament and the New Testament as well as Mahabhatara (Hindu Holy Book). In Judaism, fasting is observed in several annual days, primarily on days of penitence (such as Yom Kippur, the Day of Atonement) or mourning. Fasting for Jews means completely abstaining from food and drink, including water.
