Does the intentional emission of madhiy (pre-seminal fluid) or maniy (semen), while ignorant of the ruling, invalidate the fast in the two-month expiatory fast according to the Maliki school, and does it necessitate repeating the entire expiatory fast, or only making up that day?

It is well-known in the Maliki school that intentionally expelling pre-seminal fluid (madhy) invalidates the fast. However, there are other opinions within the school that do not consider it invalidating, such as the view that making up the fast is recommended, not obligatory. This aligns with the opinion of the majority of scholars. Therefore, the questioner can adopt this opinion and consider her fast valid to avoid hardship, especially given the excuse of ignorance in some cases. As for intentionally expelling semen (maniy), it invalidates the fast without any disagreement in the Maliki school.
