I mentioned it to the prophet (May peace be upon him), or the fact was mentioned to him (by someone else). The Messenger of Allah (May peace be upon him) said; Do not do so. When you find prostatic fluid, wash your penis and perform ablution as you do for your prayer, but when you have seminal emission, you should take a bath.
