Fasting in Islam is categorized into different rulings outside of Ramadan. Understanding these classifications helps Muslims observe their fasts appropriately.
Categories of Non-Ramadan Fasting
Understanding the various types of fasting beyond Ramadan is essential for Muslims striving to deepen their spiritual practice. Below are the main categories to keep in mind:
- Obligatory Fasting This includes:
- Fasting during the month of Ramadan
- Fasting to fulfill a vow (nadhr)
- Making up missed Ramadan fasts
- Recommended (Voluntary) Fasting Voluntary fasting brings immense spiritual rewards. Examples include:
- Fasting on Mondays and Thursdays
- Fasting three days of each lunar month
- Fasting on the Day of ‘Arafah and the Day of Ashura
- The best form of voluntary fasting is fasting every other day, known as the fast of Prophet Dawood (David) — عليه السلام.
(Narrated by Muslim, 1162) - Prohibited Fasting Some fasts are forbidden, such as:
- Fasting on the two Eids (Eid al-Fitr and Eid al-Adha)
- Fasting on the Days of Tashreeq (the three days after Eid al-Adha) except for pilgrims performing Hajj
- A woman fasting without her husband’s permission when he is present
(Narrated by Bukhari, 5195) - Disliked (Makruh) Fasting
- Fasting on Fridays alone is generally disliked unless preceded or followed by another fasting day.
(Narrated by Bukhari, 1985) - Permissible Fasting
- This refers to fasting on days not specified by any particular command or prohibition, such as fasting on Tuesdays or Wednesdays.
Types of Voluntary Fasting
Voluntary fasting, a type of non-Ramadan fasting, can be divided into two categories:
- Unrestricted Voluntary Fasting
- This can be observed on any day outside of prohibited days.
- The Prophet Muhammad — صلى الله عليه وسلم — said:
(Narrated by Bukhari, 2840) - Restricted Voluntary Fasting
- Examples include:
- Six days of Shawwal
- The Day of ‘Arafah
- Fasting most of the month of Sha’ban
- Examples include:

Can Voluntary Fasting Be Observed Before Making Up Missed Fasts?
Most scholars permit voluntary fasting before making up missed Ramadan fasts, as the time for making up missed fasts is broad. Aisha — رضي الله عنها — said:
“I would have days to make up from Ramadan, but I would not be able to do so except in Sha’ban.”
(Narrated by al-Nasa’i, 2318)
While it is better to prioritize making up missed fasts since they are a debt, it is permissible to engage in voluntary fasts beforehand. Some scholars, however, discourage this practice, especially when observing specific voluntary fasts like the Day of ‘Arafah, due to its limited timing.
