Sunnah – Sunday 2nd Oct. 2011
Fasting on Mondays:
Abu Qatadah (Radia-Allaahu ‘anhu) narrated that Allah’s Messenger (Salla-Allaahu ‘alaihi wa sallam) was asked about the fasting on the day of Arafah, where upon he said, “It expiates the sins of the preceding year and the coming year.” And he was asked about fasting on the Day of Ashura, where upon he said, “It expiates the sins of the preceding year.” He was then asked about fasting on Mondays, where upon he said, “That is the day on which I was born, on it I was commissioned with Prophet hood, and on it (The Qur’an) was revealed to me.” [Muslim]
The Prophet (Salla-Allaahu ‘alaihi wa sallam) did not elaborate on the reward of fasting on Monday but the Hadith emphasizes the desirability of fasting on Monday, because the Prophet (Salla-Allaahu ‘alaihi wa sallam) has mentioned that he was born on it, and he was commissioned with Prophet hood and on it the Qur’an was revealed on him. This indicates that fasting Monday has significance, because mentioning those, benefits the servants of Allah.
Fasting on Mondays and Thursdays
Narrated Abu Hurairah (Radia-Allaahu ‘anhu) that Allah’s Messenger (Salla-Allaahu ‘alaihi wa sallam) said: “Deeds of people are presented (to Allah) on Mondays and Thursdays. So I like that my actions be presented while I am fasting.” [At-Tirmidhi]
Aishah (Radia-Allaahu ‘anha) narrated that Allah’s Messenger (Salla-Allaahu ‘alaihi wa sallam) used to observe fast on Mondays and Thursdays.
Fasting Monday is more stressed than fasting on Thursday. Fasting Mondays and Thursdays is Sunnah. Fasting on Tuesday or Wednesday is not Sunnah nor is it disliked.
Fasting any three days in a month
It was narrated that Abu Hurairah (Radia-Allaahu ‘anhu) said: My close friend the Prophet (Salla-Allaahu ‘alaihi wa sallam) advised me to do three things which I will not give up until I die: fasting three days of each month, praying Duha and going to sleep after Witr. [Narrated by al-Bukhaari and Muslim]
Shaykh Muhammad ibn Saalih al-‘Uthaymeen (Rahimahullah) said that it is permissible to fast these days one after the other or separately, and they may be at the beginning of the month, or in the middle, or at the end.
Fasting al-ayyaam al-beed (i.e. Fasting the 13th, 14th & 15th of each month)
Jareer ibn ‘Abdullaah (Radia Allaahu ‘anhu) narrated that the Prophet (Salla-Allaahu ‘alaihi wa sallam) said:
“Fasting three days of each month is fasting for a lifetime, and ayaam al-beed are the thirteenth, fourteenth and fifteenth.”
