How can clothes be stained by semen before being stained by prostatic fluid (madhy), given that prostatic fluid (madhy) is inevitably discharged before semen, and prostatic fluid (madhy) is impure while semen is pure, based on Aisha's narration in Sahih Muslim that she used to rub semen off the garment of the Messenger of Allah, may Allah's prayers and peace be upon him?

The answer to the problem raised regarding the purity of semen despite being preceded by pre-seminal fluid (madhy) is summarized in several points:

First, the claim that the discharge of madhy before semen is inevitable is incorrect. Intense arousal can lead to the emission of semen without madhy, as in the case of a wet dream.

Second, even if this premise were true, madhy is a small amount and is consumed within the pure semen, thus not affecting it. Furthermore, a small amount of madhy mixed with semen is overlooked with even greater reason.
