Is the acceptance of adhkar (remembrance of God) contingent upon purity if they were vowed after prayer? And is expiation (kaffarah) obligatory for missed prayers and adhkar from the past period if the questioner was unaware of the ruling? And how can one differentiate between maniyy (spermatic fluid) and madhiy (pre-seminal fluid) for someone who is not an expert, and is ghusl (ritual bathing) required for everything that exits without intercourse or masturbation?

Repeated questioning may be an indication of waswas (obsessive whispering), so it should be avoided. Regarding the vowed adhkar (remembrances) after prayer, ritual purity (taharah (definition)) is not a condition for them unless it was intended at the time of the vow. Purity is a condition for the validity of prayer, and if you pray without it, despite being able to attain it, you incur sin for abandoning prayer and for abandoning the vowed adhkar. Ignorance in such matters does not excuse one from the obligation of expiation (kaffarah (definition)), as in the hadith (definition) about expiation for sexual intercourse in Ramadan (definition). The expiation here is for delaying the fulfillment of the vow, and its obligation is a view held by the Hanbalis, which is the more cautious opinion. However, it is permissible to adopt the view that it is not obligatory and that merely making up for it suffices. Mani (sperm) and madhi (pre-ejaculatory fluid) have distinct characteristics. Discharges after lustful thoughts are often madhi. Mani may be discharged merely by thinking or without any cause, and if it is discharged without pleasure, ghusl (definition) (ritual bath) is not required.
