What is the term for a voluntary fast performed outside the obligatory month of Ramadan, such as on Mondays and Thursdays?

Explanation

– Sawm Nafl refers to a voluntary fast performed outside the obligatory month of Ramadan, such as the commonly recommended practice of fasting on Mondays and Thursdays throughout the year.
– Various Hadiths describe additional recommended voluntary fasts, including fasting on the day of Ashura, the six days of Shawwal, and specific days within Dhul Hijjah.
