Eid Al-Fitr is celebrated at the end of Ramadan (a month of fasting during daylight hours), and Muslims usually give zakat (charity) on the occasion.
Ramadan is the holy month in which Muslims must fast from dawn to sunset primarily as a devotion to the commandment of Allah ( this includes flattery-free fasting, prayer and charity as well), but also to harvest the healthy benefits of fasting ( Self-Enlightenment, Immune System Boost, brain function and Insulin Sensitivity Improvement). Contrary to the false idea that fasting is done so people feel what the poor and the hungry go through, the needy also fast for Ramadan, as prescribed by Muslim scholars.
Muslims fast by denying themselves food, water and all related sexual activity with their spouses, but also many things religiously forbidden but socially forgotten can void the person’s fast, such as Ghibah (backbiting others) and deceiving others. However, people with chronic diseases or unhealthy conditions such as diabetes for example, and those who haven’t reached the age of puberty are exempt from fasting. Travelers, and women who are menstruating or nursing a baby, are exempt from fasting as well during their special situation but are required to fast later.
Taqobbalallahu minna wa minkum, Happy Eid Al Fitr
