Keeping six fasts of Shawwal after Ramadan is a cause of great virtue. The Holy Prophet ﷺ said that whoever fasts in Ramadan and then fasts six days of Shawwal after that, it is as if he fasted for the whole year.
Virtue:
Reward equal to fasting for the whole year
Increase in good deeds and elevation of ranks
A means of making up for the deficiency of Ramadan
Recommended Method:
Six fasts can be kept at any time during the month of Shawwal
It is better to keep them continuously, but it is also permissible to keep them separately
If there are missed fasts to make up, it is better to complete them first
May Allah Almighty grant us the ability to appreciate these blessed fasts and act accordingly. Amen 🤲
