I know Muslims fast in Ramadhan. Why do you fast the whole month not eating and drinking anything during the day?

Fasting the whole month of Ramadan is the fourth pillar in Islām. This month is the 9^th lunar month of the Islamic calendar and is the month in which the Qur’ān was revealed. For the whole month Muslims fast from dawn until sunset. During the Prophet’s life, the Angel Gabriel would descend every night of the month and go over the verse that had been revealed up to that point with him. In additional to the spiritual cleansing of the soul, fasting has many religious, social, cul-tural, economic and educational benefits to all – including the control of egos, appetites and lusts. Fasting has also been prescribed on other people before Islām too, like the Jews and Christians.
