Does a drop of seminal fluid (manī) coming out of the penis without ejaculation while a husband is caressing his wife invalidate the fast?

The emission of semen necessitates ghusl (definition) (ritual bath) and invalidates the fast, requiring abstention (from food and drink) and making up the fast. As for pre-seminal fluid (madhy), it does not invalidate the fast according to the majority of scholars. It necessitates washing the penis and performing ablution (wudu), based on the Prophet's (peace be upon him) saying: "Perform ablution and sprinkle water on your private parts." However, the Malikis held the view that it does invalidate the fast, and adopting their opinion is more cautious.
