Missing out on consistent spiritual rewards throughout the year? 

You're not alone.

Many Muslims focus on Ramadan and Ashura but overlook simple monthly acts that carry immense rewards. The routine of everyday life often takes over, and opportunities to earn Allah’s blessings quietly pass by.

But there’s a powerful Sunnah—fasting the White Days—that brings you closer to Allah every single month.

Let’s explore the meaning, benefits, dates, and fasting guidelines of the White Days in Islam.

What are the Three White Days in Islam?

The Three White Days in Islam, or Ayyam al-Bid, refer to each lunar month's 13th, 14th, and 15th. 

These days are considered spiritually significant due to their association with the full moon, which illuminates the night sky. The term "White Days" refers to their radiant brightness. Fasting on these days is highly recommended for Muslims to attain immense spiritual rewards.

The moon appears fully illuminated at night, casting its glow from dusk till dawn. During the day, the sun adds to this brightness, symbolizing purity and renewal.

Allah (SWT) states (interpretation of the meaning): 

“They ask you about the new moons. Say: They are signs to determine fixed periods for people and the pilgrimage.”

[Al-Baqarah 2:189]

Prophet Muhammad (PBUH) set an example by fasting on special days other than Ramadan throughout the year as a Sunnah. He (PBUH) encouraged his followers to embrace this virtuous practice.

Among these were Mondays, Thursdays, the six days of Shawwal month, and three days of every lunar month known as the White Days in Islam. 

Abu Dharr (may Allah be pleased with him) narrated:

"The Messenger of Allah (peace be upon him) commanded us to fast three days each month. These are the days of the full moon: the 13th, 14th, and 15th of the lunar month."

(An-Nasa’i and At-Tirmidhi, authenticated by Ibn Hibban)

Abdullah bin ‘Amr bin Al-‘As reported:

"Observing Saum (fasting) on three days of every month is equivalent to a full month’s fasting."

(Al-Bukhari and Muslim)

How can fasting for three days be equivalent to fasting for 30 days? Because for the Ummah of Prophet Muhammad (PBUH), every good deed is rewarded tenfold!

An additional significance stems from a profound event in which Allah forgave Prophet Adam (AS) during these days, cleansing his record. For Muslims, the White Days, as highlighted by Prophet Muhammad (PBUH), offer a unique opportunity for worship, reflection, and seeking Allah's mercy.

Why Lunar Dates Matter in Islam?

Certain acts of worship, like fasting and calculating iddah (the waiting period after divorce or widowhood), are tied to the lunar calendar. These follow Islamic months, not the solar months of the Gregorian calendar.

If you fasted according to the solar calendar, those fasts may not align with the lunar calendar. However, any voluntary fast done sincerely for Allah’s sake is still rewarded. To gain the specific reward for fasting al-Ayyam al-Bid, as encouraged by the Messenger of Allah (PBUH), it is crucial to follow his guidance.

Expert Tip

Use the lunar calendar to determine the dates and observe these fasts accordingly.

Fasting the White Days is a voluntary act of worship. Voluntary deeds bring one closer to Allah and earn His love, as mentioned in the hadith:

"My servant does not draw near to Me with anything more beloved than what I have obligated upon him. Then, he continues with nawafil (voluntary acts) until I love him. When I love him, I become his hearing, sight, hand, and foot, guiding him in all he does."

(Al-Bukhari)

This love results in divine protection, blessings, and the promise of peace in this life and the Hereafter:

"Unquestionably, [for] the allies of Allah there will be no fear concerning them, nor will they grieve. Those who believed and feared Allah. For them is good news in this worldly life and the Hereafter. That is the ultimate triumph." 

(Quran 10: 62-64)

Hadiths about the Rewards of Voluntary Fasting

The benefits of fasting White Days reflect the immense value of voluntary worship, with rewards known only to Allah. 

1. Fasting Is Uniquely Rewarded by Allah

  • The Prophet (Peace and blessings be upon him) said:
     "Fasting is Mine, and I will reward it." (Al-Bukhari: 1904)
  • He (PBUH) also said:
     "Take to fasting, for there is nothing equal to it." (Sunan An-Nasa’i)
  • "Anyone who fasts a day for the sake of Allah and then dies will enter Paradise." (Ahmad, 5/391; see also Sahih al-Targhib, 1/412)

2. Fasting Protects and Intercedes

  • "Whoever fasts one day for the sake of Allah, Allah will move his face away from the Fire a distance of seventy autumns (years)." (Ibn Majah)
  • "Fasting serves as a shield and a strong fortress against the Fire."(Ahmad, Sahih al-Targhib, Sahih al-Jami’)
  • "Fasting will act as an intercessor for the believer on the Day of Judgment, saying: ‘O Lord, I kept him from eating and drinking during the day, so allow me to intercede for him.’" (Ahmad, al-Bayhaqi)

3. Spiritual Joy and Divine Connection

  • "The fasting person experiences two joys: the joy of breaking their fast, and the joy of meeting their Lord with the reward of their fast."(Muslim, 2/807)
  • "The scent that comes from the mouth of the fasting person is more beloved by Allah than the fragrance of musk." (Muslim, 2/808)

4. The Exclusive Gate of al-Rayyan

  • "In Paradise, there is a gate called al-Rayyan, through which only those who fast will enter. Once they have entered, it will be closed, and no one else will enter through it." (Al-Bukhari, Fath, no. 1797)

5. Voluntary Fasts That Complete Obligatory Ones

  • The Prophet Muhammad (PBUH) highlighted several voluntary fasts that carry immense merit. These include:

"Voluntary fasts, such as those on 'Ashura, the Day of ‘Arafah, the White Days (Ayyam al-Bid), Mondays and Thursdays, and the six days of Shawwal. Additional fasting during Muharram and Sha’ban will make up for any shortcomings in obligatory fasts."

This hadith emphasizes the variety and consistency of Sunnah fasts available throughout the year.

In conclusion, White Days in Islam refer to the 13th, 14th, and 15th of each lunar month, marked by the full moon. They hold great spiritual importance as the Prophet Muhammad (PBUH) regularly fasted on these days and encouraged others to do the same.

Fasting on the White Days brings immense rewards, including the reward of fasting the entire year when practiced consistently. The benefits of fasting these days include increased closeness to Allah, purification of the soul, and developing self-discipline. 

In short, White Days are a monthly opportunity to earn lasting spiritual rewards by following a simple Sunnah that connects us to faith, discipline, and divine mercy.
