I would like to know about the tradition of fasting in various religions like Hinduism, Judaism, Christianity, Islam and others if any
Let us share what we know about fasting in various religions whether mandatory or voluntary, how many days, specific time of the year and calendar followed (solar or lunar) etc.
Muslims follow the Islamic Calendar based on lunar year. They fast in the 9th month (Ramadan) which is mandatory. In addition Muslims can fast voluntarily for spiritual enhancement on any day except the two Eid Days falling on the 1st of Shawwal, the month following Ramadan, and the 10th of Zil-Hajj the last month of Islamic Calendar. Fasting on for six days in the month of Shawwal and 9th & 10th day or 10th & 11th day of the first month called Moharram, The day of Arafah (9th of Zil-Hajj) and some other days is considered to be of great benefit and is considered to be a source of pleasing the God.
Fasting is disliked on the last days (29th & 30th) of Ramadan or on Fridays as a habit. It is also prohibited to single out Saturdays for voluntary fasting. Perpetual fasting is also forbidden.
The time of fasting is from the Morning when it is still absolutely dark till the sunset and during this period a Muslim cannot eat, drink or have sex.
