What Is Fasting Ayyamul Bidh? Meaning, Evidence, Intention, and Its Virtues
Fasting ayyamul bidh is a recommended sunnah fast on the 13th, 14th, and 15th of the Hijri month, except the 13th of Dzulhijjah which coincides with the Days of Tashriq. It is highly encouraged based on the hadith of Prophet Muhammad (PBUH). The Messenger of Allah said, "Fasting three days every month is like fasting the whole year" (HR Bukhari).
The intention for the fast: "Nawaitu shauma ayyamil bidl lilahi ta'ala" (I intend to fast Ayyamul Bidh for the sake of Allah the Almighty). Its virtues include getting the reward of fasting for an entire year, following the example of the Prophet, restraining desires, and receiving a direct reward from Allah SWT.
The majority of scholars recommend doing it consecutively, but it's okay to do it non-consecutively as long as it's still three days in a month.
