Fasting in Islam is much more than abstaining from food and drink—it is a profound act of worship and obedience to Allah. Literally, the word “sawm/siyam” means to abstain or refrain from something. Technically, it means to refrain from food, drink, sexual intercourse, and all that which breaks the fast from dawn to sunset, intending to do so in obedience to Allah.

1. Lessons and Moralities of Fasting

Allah, Most High, says:

“Blessed be He in whose hand is Sovereignty, and He is able to do all things. He created death and life that He may try which of you is best in deed. He is the Exalted in Might, oft Forgiving.”
(Al-Mulk 67: 1-2)

Also, He says:

“It is He who made the night and day follow each other for such as have the will to celebrate His praises or to show their gratitude.”
(Al-Furqan 25: 62)

The cycle of life and death, along with the succession of night and day, serves a purpose—to test us and to give us an opportunity to express our thanks and gratitude to our Creator and Sustainer. The month of Ramadan comes and goes, urging us to examine ourselves and discover what we can learn and achieve during this sacred period. The true test of Ramadan lies in the lasting effects it imprints on our lives:

a) Discipline

During Ramadan, we learn to discipline ourselves for the sake of Allah. A strict schedule governs our eating and drinking routines, reminding us that even the most mundane activities are under divine guidance. This disciplined lifestyle is a powerful reminder that we are not bound by our habits but are always servants of Allah. Post-Ramadan, maintaining this spirit of discipline is essential to continuing our submission to Allah’s commands.

b) Renewal of Devotional Life

Ramadan revitalizes our enthusiasm for worship and devotion to Allah. During this month, we are more attentive to our daily prayers and engage in special nightly prayers. Since there is no religion without prayer, Muslims learn to deepen and strengthen their religious life through focused acts of worship during Ramadan.

c) Renewal of Our Contact with the Qur’an

Ramadan and the Qur’an share an intrinsic connection. It was in this blessed month that the divine message was revealed to Prophet Muhammad (peace and blessings be upon him). Fasting prepares the hearts of believers to receive and internalize the Word of Allah. This period is ideal for deep spiritual and mental communication with the Qur’an, allowing the Muslim Ummah to embrace and follow its teachings.

d) Renewal of Our Identity with the Ummah

Fasting is not merely an individual experience—it is a communal one. The entire Muslim Ummah fasts together, fostering a strong sense of togetherness and collective obedience to Allah. Ramadan strengthens the bonds within the community by uniting individuals through acts of piety and virtue. The commitment to these values forms the foundation of a morally robust and united Muslim community.

e) A Fresh Sense of Care and Sympathy

Ramadan deepens our understanding of the hardships faced by the poor and needy. Through voluntary hunger and thirst, we experience a glimpse of the deprivation that many endure. Known as the month of charity and sympathy, Ramadan teaches us to be kinder and more generous, often marked by the increased payment of Zakah (charity).

f) Jihad or Struggle

Both fasting in Ramadan and Jihad were prescribed in the second year of Hijrah in Madinah. Fasting serves as preparation for enduring hardships and sacrifices. This experience equips Muslims to struggle against evil—whether within themselves, in society, or globally.

g) Taqwa (God-Consciousness)

In summary, the moral and spiritual benefits of Ramadan culminate in the gift of taqwa. Taqwa, the highest virtue in Islam, signifies God-consciousness, piety, and a profound commitment to all that is good. It embodies the submission to Allah and the rejection of all that is evil.

2. Who Should Fast?

Fasting during the month of Ramadan is obligatory for every Muslim, male or female, who meets the following criteria:

  • Mental and Physical Fitness: The individual must be sane and capable.
  • Age of Puberty: The fasting obligation applies from the age of puberty (typically around fourteen). Younger children should be encouraged to fast.

  • Travelers: Those on a journey should make up the missed fasting days later.
  • Women During Menstruation or Post-Childbirth Confinement: They should also make up the missed days later.

4. Requirements for the Validity of Fasting

For a fast to be considered valid, it must meet the following conditions:

  • Abstinence: One must abstain from food, drink, smoking, and sexual intercourse with one’s spouse from dawn to sunset each day in Ramadan.
  • Correct Intention: The individual must have the sincere intention to fast in compliance with Allah’s command.

5. Sunnan (Desirable Acts) of Fasting

Following the Sunnan of fasting enhances the spiritual experience:

  • Suhuur: Take the pre-dawn meal as close to the time of Fajr as possible.
  • Iftar: Break the fast immediately once the sun has set.
  • Du`aa’: Recite the supplication that the Prophet (peace and blessings be upon him) used to say at Iftar.
  • Avoid Contradictory Acts: Steer clear of any acts that contradict the spirit of fasting.
  • Engage in Good Deeds: Participate in charity, tarawih prayers, Qur’anic recitation, dhikr, and other righteous acts.
