Q: I have always suffered from the disease of urinary dribbling, but recently it has become aggravated and I have fallen into the category of ma'adhur (one with a chronic excuse). My question is a two-part question related to my current situation:
1) A few weeks ago I was praying Isha (and some other prayers along with it). Unfortunately I was also in a state of sexual excitement at the time (no erection, but just a feeling of excitement). During my prayer I felt some najasat exiting my penis several times, but since I was already ma'adhur, I continued praying. My concern is that the najasat was prostatic fluid, and the prayers became invalid.
2) On another occasion I was standing in prayer and I got this sudden urge to urinate (which was not there at the time I started Salah), and I was trying to suppress the urge and the pressure, but some urine did exit at the time. However, within less than a minute the urge just disappeared, and I continued praying (and prayed several other prayers too) with that wudhu. Does this situation also fall within the realm of my normal udhur or should I have stopped my prayer and repeated my wudhu?
