The fourth pillar of Islam is fasting during the month of Ramadan. Ramadan is the ninth month of the Islamic calendar. During this month, the Muslim must abstain from eating, drinking, and sexual intercourse from dawn till sundown.
Performing this pillar establishes patience and humility within the believer. Fasting also helps to bring a person’s carnal desires under control. A Muslim who is fasting is far less likely to commit a major sin than one who is not. In fact, there are many Muslims, who outside of Ramadan are addicted to cigarettes, yet they are able to leave them alone for a full month!
A Muslim is encouraged to fast throughout the year, but it is only during Ramadan that fasting is compulsory. Ramadan is an important month for Muslims as that is the month during which the Quran was revealed to Prophet Muhammad, may Allah be pleased with him. And the devils and evil jinn are locked up during the month of Ramadan as well.
Fasting has many other benefits. It allows the rich to experience the suffering of the poor. And since many Muslims usually break fast and pray together during the month of Ramadan, this is also a chance to further strengthen the ties of brotherhood.
