Faridatus-Sawm [The Obligatory Fasting]

Allah, the Exalted, says:

"The month of Ramadan, is that in which the Qur'an was revealed, a guidance to mankind and manifestations of guidance and distinction; therefore, whoever of you is present in the month (at home) has to fast therein; and whoever is sick or on a journey, then (he shall fast) a (like) number of other days. Allah wants ease for you, and does not want hardship for you. And that you should complete the number and that you should exalt the Greatness of Allah for having guided you, and that you may give thanks." (2:185)

He, the Glorified, also says:

"O you who believe! fasting is incumbent on you as it was incumbent on those before you, so that you may ward off Allah's wrath." (2:183).

The Messenger of Allah (s) said: "A fasting person is considered to be worshipping even if he is in his bed, unless he backbites a Muslim."1 He (s) also said: "Whoever fasts in Ramadan out of faith and to please Allah, Allah forgives the sins he had committed."2

He (s) also said: "O people! The month of Almighty Allah has come to you with blessings, mercy and forgivcness, a month which is the best of months with Allah, its days are the best of days, its nights are the best of nights and its hours are the best of hours..."3 He (s) also said: "...It is the month of forbearance, and, surely, the reward of forbearnce is Paradise. It is the month of consolation."4

The Imam Ja'far As-Sadiq (a.s.) said: "Allah enjoined the Siyam [fasting] so that equality may prevail between the rich and the poor, since the rich usually do not feel the touch of hunger so as to show mercy to the poor, as they are capable of affording whatever they desire. Therefore, Allah, the Exalted, wanted to put His creatures on an equal footing, making the rich taste the pains of hunger, so that they may be kind to the needy and have mercy on the hungry people."5

As-Sawm is a worshipping duty legislated by Allah, the Exalted, and enjoined on the people, and nations which lived before us, as it is now enjoined on us. As-Sawm is one of the fundamental pillars of Islam, and it is to be practised in a particular month of the year, the blessed month of Ramadan.

As-Sawm brings about numerous ritual, educational and moral objectives. It teaches man to prefer obeying Allah and loving Him to loving himself, his desires and pleasures. The Muslim, in this month, responds to Allah's command, by giving up all pleasures derived from food, drink, etc., for the sake of Allah's pleasure and as an obedience to His orders.

It strengthens one's will and ability to forbear difficulties and sharpens one's inner sense of obeying and carrying out the Divine orders and laws. The Sa’im [the fasting person] is inwardly driven to avoid all that Allah had ordered him to avoid in this blessed month. This accustoms the Muslim to obedience and commitment.

It also teaches the Sa'im Muslim to adhere to the virtuous morality and upright conduct. It causes the rich Sa'im, to sense the poor's hunger, and to understand the meaning of being poverty-stricken and needy. This, in turn, urges him to help the poor and soothe their pains. Furthermore it makes all Muslims feel equal in the presence of Allah, the Exalted, and, by strengthening this feeling in them, they learn to regard one another as brothers, equal in rights and duties.

There are, of course, many other good effects and salubrious (healthful), curing advantages to the body. The Messenger of Allah (s) said "Sumu Tasihhu" that is: Fast yow would be healthy. It has been proved by the physicians and scientists that fasting is a relaxation for the body's organs, and is regarded as a cure for many diseases.

The Conditions Making Fasting Wajib

Fasting can not become Wajib on a Muslim unless the following conditions are present:

1. Puberty: Fasting is not incumbent on a person who has not yet reached puberty, though it would be correct if he fasted;

2. Sanity: No fasting is incumbent on the insane.

3. Not being a traveller: One who is on a journey is not to fast, and if he did it, it would be Batil.

4. Consciousness, as the unconscious person is not to fast.

5. Cleanliness from Hayd and Nifas, as the women who are in the state of Hayd or Nifas are not to fast before becoming Tahir, otherwise, their fasting would be Batil and unacceptable, if they did fast during the Hayd and Nifas.

6. Being healthy enough to withstand fasting, as the sick, the old men and women (for whom it is difficult to fast), and the pregnant6 and the suckling women who or whose children would be harmed by fasting, are not to fast.

N. B. The Musafir, the sick, the Hayd and the nafsa must perform the Qada Sawm, that is to fast, when able later on, as many days as had been missed.

The Niyyah for Fasting

1. The Niyyah is a basic part of the Sawm, as the sa'im will have to make his intention that he is performing the Sawm for the pleasure of Allah; the Exalted.

2. The Niyyah can be made once by the Sa'im for the whole month of Ramadan, or one may make it for each day separately, before dawn.

3. The Niyyah for fasting is to last until the end of the day. If one has the intention of breaking one's fast during the day, or if one is not sure about it, one's fasting will be Batil, even if one did not do any of the acts which invalidate the Sawm such as eating, drinking, etc. In this case one has to abstain from the "invalidators" until the end of the day, and then to make up for it by fasting another day after the month of Ramadan.

When to Begin and End Ramadan Fasting

The blessed month of Ramadan is the month of the Sawm which is incumbent on every Muslim Mukallaf Therefore, it is necessary to be sure about the first and last days of this month, in order to carry out this sacred worship.

The Islamic Shari’ah has explained the lawful ways of knowing these two days at the beginning and the end of the month. These ways are as below:

1. The month of Ramadan is ascertained by eye-witnessing the Hilal (crescent) [the new moon] and the day of the Eid is also ascertained by eye-witnessing the new moon of the month of Shawwal [the month after Ramadan]

2. If the new moon of the month of Ramadan could not be seen for any given natural reason, such as clouds, fog, or dust, the number of the days Sha'ban [the month before Ramadan] is to be completed 30 days, then we start the month of Ramadan the next day.

3. The Eidul-Fitr [the first day of the month of Shawwal] is ascertained by eye-witnessing the new moon on the begin ning of the month of Shawwal. If it was not possible to see it, the month of Ramadan is to be completed up to 30 days.

How to Ascertain the Hilal (The New Moon)

There are three ways defined by the Islamic Shari’ah for being sure of the visibility of the Hilal, (the crescent):

1. If someone himself saw the Hilal, it would be Wajib upon him to start the Siyam of the month of Ramadan, or to break the fast, if it was the Hilal of Shawwal.

2. If two equitable men7 testified that they themselves had seen the Hilal, we, then, would have to begin our Siyam, or to break it.

3. If it was rumoured among people that the Hilal had been seen, and people gave credit to it and believed in it, then the Mukallaf must act according to this circulation, starting the Siyam, or by starting the Iftar [fast-breaking], depending on the circulation.8


Some Faqihs believe that to ascertain the crescent in a country cannot be sufficient for the citizens of another, unless both are near each other, or they were known to have a common horizon, or the ascertaining country is situated to the east of the other. Whereas other jurisprudents believe that ascertaining of in a country suffices for ascercaining of it in the other countries.
