VoluntaryFasts.jpgThe first thing to understand is the difference between what is known as fard and what is known as nafl.  Fard is obligatory, it is what Allah requires us to do, and leaving it is a sin and we will be held accountable for it.  An example is two rakah of Fajr prayer and the fasts of Ramadan.

Nafl literally means extra.  Nafl worship is voluntary, it is not required from a Muslim, rather it is up to the individual to offer it.  It is optional and voluntary.  The Muslim is not sinful for neglecting nafl, but is rewarded for doing it.  Therefore, nafl worship is recommended.  Examples of nafl fasts will be covered in this lesson.

Many times a new Muslim is anxious about fasting the whole month of Ramadan (9thIslamic month).  Voluntary fasts provide an excellent opportunity to practice fasting while earning rewards before Ramadan approaches.  At the same time, one must remember not to burn out, but to be gradual without being negligent.

The Most Important Nafl Fasts

1.Six Days in the Month of Shawwal (the month following Ramadan or the 10th Islamic month)

The Prophet said

Whoever fasts during the month of Ramadan and then follows it with six days of Shawwal will be (rewarded) as if he had fasted the entire year

Saheeh Muslim

It is forbidden to fast on the day of Eid or Eid-ul-Fitr to be specific.  You can keep these six fasts anytime after the day of Eid and they do not have to be kept consecutively.   If you wish you can fast them separately as long as they are completed within the month of Shawwal.

2.Fasting the Ninth Day of Dhul-Hijjah (12th Islamic month)

The Islamic month in which the Hajj is performed is known as Dhul-Hijjah.  Yaum ul-Arafah or the “Day of Arafah” is the ninth day of that month. 

It is recommended for those not performing the Hajj pilgrimage to fast this day as

the Messenger of Allah said

Fasting on the day of Arafah is an expiation for two years, the year preceding it and the year following it

Saheeh Muslim

3.Fasting the Tenth Day of the Islamic Month of Muharram (1st Islamic month)

Muharram is the first month of the Islamic lunar calendar.  The tenth day of this month has a special name – “Ashura.” What does one get for fasting it?

The Prophet informed us

Fasting the day of Ashura is an expiation for the past year

Saheeh Muslim

4. Fasting Mondays and Thursdays

Abu Hurairah, the close companion of Prophet Muhammad, reported that the Prophet would fast on Mondays and Thursdays.  When asked about that, the Prophet, may the mercy and blessings of Allah be upon him,


The actions are presented on every Monday and Thursday.  Allah forgives every Muslim or every believer, except for those who are boycotting each other.  He says (about them): ‘Leave them


When the Prophet was asked about fasting on Mondays,

he said

That is the day on which I was born and the day on which I received revelation.”[5]

Saheeh Muslim

5.Fasting most of the month of Sha’ban (8th Islamic month)

Sha’ban is the name of the Islamic month that comes before Ramadan.  The Prophet would fast most of the month of Sha’ban

‘Aisha, the wife of

the Prophet said

I never saw the Messenger of Allah fast a complete month except for Ramadan, and I have never seen him fast more in a month than he did in Sha’ban

Saheeh Al-Bukhari, Saheeh Muslim

Differences Between Fasts of Ramadan & Voluntary Fasts

1.    The intention for a voluntary fast can be made during the day

Let us say that you woke up and prayed Fajr.  You did not have the intention to fast that day and you also did not eat, drink, have intercourse, or otherwise do anything that would break a person’s fast.

Later in the day, you can make the intention for a voluntary fast if you have not done any of those things that break the fast.  This is based on ‘Aishah’s hadith

The Prophet came to us one day and said: ‘Do you have any (food)?’ We said, ‘No.’ He said: ‘Therefore, I am fasting

Saheeh Muslim, Abu Dawud

You must have the intention the night before to fast the next day for Ramadan fasts.

2.    It is permissible for one who is performing a voluntary fast to break his fast

The Prophet said

The one who is fasting voluntarily is in charge of himself.  If you wish you may fast and if you wish you may break your fast


Abu Sa’id al-Khudri said

I prepared food for the Prophet.  He came to me with some of his companions.  When the food was laid out, one of the men said: ‘I am fasting.’ The Messenger of Allah said: ‘Your brother has invited you and incurred expenses in your behalf.’ Then he asked him, ‘Break your fast and fast another day in its place if you wish


Breaking a day of fasting during the month of Ramadan without a legitimate reason, on the other hand, is a serious sin even if the person makes it up later.
