I used to suffer greatly from the discharge of prostatic fluid, so I would frequently perform the full bath because of it. I mentioned this to the Messenger of Allah ﷺ and asked him about it.He said, "Performing ablution is sufficient for you in that case."I asked, "Messenger of Allah, what about what gets onto my clothes from it?"He replied, "It is enough for you to take a handful of water and sprinkle it on the area of your garment where you see it has touched."

كنت ألقى من المذي شدة وعناء فكنت أكثر منه الغسل فذكرت ذلك لرسول الله ﷺ وسألته عنه فقال إنما يجزئك من ذلك الوضوء فقلت يا رسول الله كيف بما يصيب ثوبي منه قال يكفيك أن تأخذ كفا من ماء فتنضح به ثوبك حيث ترى أنه أصاب منه

Ibn Ishaq explicitly stated that he heard it directly, as found in Abu Dawud (210).
