Answer:
Sawm is one of the five pillars of Islam and therefore mandatory during Ramadan. However, Muslims can keep the Sawm any time of the year as a form of worship, or in order to make up for lost fasts. The Islamic calendar operates on the lunar cycle, as opposed to the Gregorian one we use in modern day.Faith or belief in Islam is the foundation of human life. In fact, the beliefs that all of us have shape and mould our lives regardless of what religion or way of life we ascribe ourselves to. These beliefs determine how we think, act and perceive life in general.
