"I was one who had a lot of prostatic discharge, and the Messenger of Allah ﷺ said to me: 'If you see Madhi (prostatic fluid) then wash your penis and perform Wudu' like that for Salah, but if you ejaculate semen, then perform Ghusl.'"  

لِي رَسُولُ اللَّهِ ﷺ إِذَا رَأَيْتَ الْمَذْىَ فَاغْسِلْ ذَكَرَكَ وَتَوَضَّأْ وُضُوءَكَ لِلصَّلاَةِ وَإِذَا فَضَخْتَ الْمَاءَ فَاغْتَسِلْ

كُنْتُ رَجُلاً مَذَّاءً فَسَأَلْتُ النَّبِيَّ ﷺ فَقَالَ إِذَا رَأَيْتَ الْمَذْىَ فَتَوَضَّأْ وَاغْسِلْ ذَكَرَكَ وَإِذَا رَأَيْتَ فَضْخَ الْمَاءِ فَاغْتَسِلْ
