What is the ruling on the emission of prostatic fluid (madhiy) – without desire – when speaking with one's fiancée, and does this affect voluntary or obligatory fasting?

The fiancée is a stranger to her fiancé, so it is not permissible to converse with her except out of necessity and while observing the Sharia guidelines. Conversing with her for enjoyment and pleasure from her voice is unlawful. The emission of madhy (pre-seminal fluid) due to this necessitates repentance. Madhy does not invalidate the fast according to the majority of scholars. It is obligatory to avoid conversing with her unnecessarily, especially while fasting. What is mentioned about conversation between fiancés being a means for each to truly know the other is often mere illusion and deception.
