The fourth pillar of Islam is fasting in the month of Ramadan, the month in which the Qur’an was revealed, in solidarity with the poor, and as a spiritual exercise cultivating qualities of discipline, self-denial and non-indulgence. This is the month in which Muslims abstain from food, drink and sexual activity between dawn and dusk, and busy themselves with the practice of the Divine Remembrance (dhikr), and reading and reflecting upon the Qur’an. Yet it is also a month of material blessings and joy, and after dark, a festival month of gatherings of families and friends, and of true appreciation of the gift of food and drink. As a hadith states “a person who fasts has two joys; joy when he breaks his fast, and joy when he meets his Lord” that is, in the Hereafter.
