Allah the Almighty has constructed the universe upon a certain balance and has likewise ordered this balance upon humanity. The great religion of Islam offers perfect guidance for every branch of our lives. It offers a program of action for everything that it prescribes.
The primary objectives of Salah, Zakah, and Fasting are to bring us closer to Allah and inculcate Taqwa (piety and self-restraint) within us. But the fact is that when Islam is taken as a unitary whole and its entire program implemented, each of its pillars reinforces the other and serves multiple purposes.
Fasting in Ramadan is a part of the broader program that Islam prescribes for man to fulfill his moral and spiritual destiny in this world and in the Hereafter. It is a special worship designed to develop in man the ability to exercise self-restraint and patience for the pleasure of Allah Almighty.
Thus, denying or ignoring fasting intentionally excludes a person from the fold of Islam. Ibn Abbas (may Allah be pleased with him) reported that: Allah’s Messenger (Peace and Blessing of Allah be upon him) Said:
“The roots of Islam and the foundations of the Deen (religion) are three, upon them Islam is built, whoever leaves one of them has disbelieved in them and his blood is lawful: Testifying that none has the right to be worshipped but Allah, the prescribed prayers, and fasting in Ramadan. ” (AbuYa’la, Ad Daylami, and verified by Ad Dhahabi)
Ad Dhahabi said: With the believers, it is agreed that whoever leaves a fast in Ramadan without sickness he is worse than the adulterer and the addicted drinker.
