A Series of Reminders About The Month of Sha’bān

When It Is Permissble To Fast Yawm Ash-Shak (The Day of Doubt) & When It Is Harām To Do So?

Imam Ash-Shāfi’ī رحمه الله said: “I do not like that someone intentionally seeks out fasting Yawm Ash-Shak (the Day of Doubt) optionally. As for the one who is making up a missed fast or is regular fasts coincided with this day, then there is no problem to fast it.

An-Nawāwī رحمه الله said: “If he fasted Yawm Ash-Shak (the Day of Doubt) as an optional fast and he had reason to do so because he would usually fast the white days (i.e. 13th, 14th, 15th of every Islāmic month), or he would fast a day and eat the other day (i.e: the fast of Dāwud), or he would fast specific days like Mondays and Thursdays and Yawm Ash-Shak (the Day of Doubt) coincided with his regular fasting then it is permissible for him to fast this day. However, if he did not have reason to fast this day then to fast it is harām.
