What is the 4th pillar sawm?

The 4th pillar of Islam is Sawm, which refers to fasting during the holy month of Ramadan. Muslims abstain from food, drink, smoking, and marital relations from dawn until sunset as a means of spiritual reflection, self-discipline, and empathy for the less fortunate. Sawm is also a time for increased prayer, reading of the Qur'an, and community engagement. This practice emphasizes purification of the soul and fosters a sense of unity among Muslims worldwide.
