Is Fasting Certain Days Recommended?



Reply Date

As-salamu `alykum. Are there certain days to fast in the week as a Sunnah or is it a bid`ah (innovation in religion)? Some books say it is a Sunnah to fast Mondays, Thursdays, and 13th, 14th and 15th of each month. Does that mean those days are special in the week and month or holier? Could you explain this, please?



Wa `alaykum As-Salamu wa Rahmatullahi wa Barakatuh.

In the Name of Allah, Most Gracious, Most Merciful.

All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.

In this fatwa:

The Prophet (peace and blessings be upon him) has exhorted us to fast during certain days: six days of Shawwal, the first ten days of the month of Dhul-Hijjah, especially the day of Arafah for those who are not performing Hajj,

Abu Hurairah (may Allah be pleased with him) reported that the Prophet (peace and blessings be upon him) used to fast on Monday and Thursday. Being asked about that the Prophet said, “Deeds are presented on every Monday and Thursday. Allah forgives every Muslim or every believer, except for those who are forsaking each other. He says [about them]: ‘Leave them.’” (Ahmad)

It is reported that the Prophet (peace and blessings be upon him), when asked about fasting on Monday, said: “

As for fasting the 13th, 14th, and 15th of each month, Abu Dharr Al-Ghafari reported, “The Messenger of Allah ordered us to fast for three days of every month – that is, on the days of the full moon (the 13th, 14th, and 15th of the lunar month). And he said, ‘It is like fasting the whole year.

So, dear brother, it’s clear that observing fasting on those days moves in line with the practice of the noble Prophet (peace and blessings be upon him) who set a shining example for Muslims to follow, in compliance with Allah’s words, {You have indeed in the Messenger of Allah a beautiful pattern (of conduct) for any one whose hope is in Allah and the Final Day, and who engages much in the Praise of Allah.} (Al-Ahzab 33:21)

Allah Almighty knows best.
