What is the ruling on fasting on the Day of Doubt?
Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
Fasting on the Day of Doubt has been a subject of scholarly disagreement regarding its permissibility. The Salaf (early generations of Muslims) unanimously agreed that fasting on the Day of Doubt is not obligatory. The majority of scholars disliked fasting on this day, except for someone who has a habitual fast that falls on this day, or someone who fasts continuously and that day happens to coincide with their fasting, or if it is for making up a missed fast that is due upon them.
