What is the ruling on the fast of one who found something whose characteristics of semen—pleasure, gushing, and relaxation—were not confirmed, after he spoke with girls online for the purpose of da‘wah (proselytizing) in Ramadan? And what is the ruling on continuing this da‘wah? And what is the ruling on the fast of one who performed ghusl (ritual bathing) during the day in Ramadan and used fragrant materials like shampoo and soap?

If something is discharged as a result of conversing with girls, then if it is maniyy (spermatic fluid), ghusl (ritual bath) is required. If it is madhiy (pre-seminal fluid), then washing the garment and body is required. If one is in doubt, he has a choice. The fast is not invalidated by the emission of madhiy. As for maniyy, it invalidates the fast if discharged through direct physical contact, but not through conversation, looking, or thinking. Therefore, your fast is valid in this case. Conversing with girls online is permissible provided there is no fear of fitna (temptation/strife), the conversation adheres to the limits of Islamic etiquette, and the username does not indicate gender identification. However, if one fears fitna for himself, then it is not permissible. Using perfumes and scented soap while fasting does not invalidate it.
