Hadith.150 - It has been narrated that pre-seminal fluid (madhi) and post-urinal fluid (wadhi) are akin to saliva and mucus, so neither the garment nor the private parts need to be washed because of them.
These are four things: Semen (mani), pre-seminal fluid (madhi), post-seminal discharge (wadhi), and a fluid discharged after urination (wudi).
Semen is a thick, gushing fluid that necessitates a full ritual bath (ghusl janabah).
Madhi is what comes out before semen, wadhi is what comes out after semen, and wudi is what is discharged after urination. None of these, except semen, require a ritual ghusl), nor ablution (wudu), nor the washing of clothing, nor the washing of anything that comes into contact with the body.
