The White Days are the 13th, 14th, and 15th of each Hijri month, named for the bright moonlit nights around the full moon. Fasting these three days is a recommended Sunnah and a practical way to maintain regular voluntary fasting.
Recommended actions
- Fast the 13th, 14th, and 15th of Rajab if health and circumstances allow.
- Make the intention for voluntary fasting and take suhur.
- Add Qur’an, dhikr, du‘a, and charity without neglecting obligations.
- If unable to fast all three, fast other permissible days to maintain the general Sunnah of three monthly fasts.
