Purification (Kitab Al-Taharah)
Dawud :: Book 1 : Hadith 210
Narrated Sahl ibn Hunayf:
I felt greatly distressed by the frequent flowing of prostatic fluid. For this reason I used to take a bath very often. I asked the apostle of Allah (peace_be_upon_him) about this. He replied: Ablution will be sufficient for you because of this. I asked: Apostle of Allah, what should I do if it smears my clothes. He replied: It is sufficient if you take a handful of water and sprinkle it on your clothe when you find it has smeared it.
