Hadith.1876 - Rifa'ah ibn Musa asked Abu Abdullah (as) about a man who touched his female servant during the Month of Ramadan and emitted pre-ejaculatory fluid (madhy).
Imam (as) said: "If it was unlawful, then he must seek Allah’s (swt) forgiveness with the repentance of one who will never repeat it, and he must fast one day in place of that day."
