ذِكْرُ إِيجَابِ الْوُضُوءِ مِنَ الْمَذْيِ وَالِاغْتِسَالِ مِنَ الْمَنِيِّ

My prostatic fluid flowed excessively. I used to take a bath until my back cracked (because of frequent washing). 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.  

كُنْتُ رَجُلاً مَذَّاءً فَجَعَلْتُ أَغْتَسِلُ حَتَّى تَشَقَّقَ ظَهْرِي فَذَكَرْتُ ذَلِكَ لِلنَّبِيِّ ﷺ أَوْ ذُكِرَ لَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ لاَ تَفْعَلْ إِذَا رَأَيْتَ الْمَذْىَ فَاغْسِلْ ذَكَرَكَ وَتَوَضَّأْ وُضُوءَكَ لِلصَّلاَةِ فَإِذَا فَضَخْتَ الْمَاءَ فَاغْتَسِلْ  

I was a man who emitted a great deal of madhi and I started to do ghusl in the winter, until the skin of my back became cracked. I mentioned that to the Prophet ﷺ, or it was mentioned to him, and he said: “Do not do that. If you see madhi, then wash your private part and do wudoo’ as for prayer, but if water gushes out, then do ghusl.ʿ  

كُنْتُ رَجُلًا مَذَّاءً فَجَعَلْتُ أَغْتَسِلُ فِي الشِّتَاءِ حَتَّى تَشَقَّقَ ظَهْرِي قَالَ فَذَكَرْتُ ذَلِكَ لِلنَّبِيِّ ﷺ أَوْ ذُكِرَ لَهُ قَالَ فَقَالَ لَا تَفْعَلْ إِذَا رَأَيْتَ الْمَذْيَ فَاغْسِلْ ذَكَرَكَ وَتَوَضَّأْ وُضُوءَكَ لِلصَّلاةِ فَإِذَا فَضَخْتَ الْمَاءَ فَاغْتَسِلْ  

"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.'" (Using translation from Nasāʾī 193)   

رَسُولُ اللهِ ﷺ لَا تَفْعَلْ إِذَا رَأَيْتَ الْمَذْيَ فَاغْسِلْ ذَكَرَكَ وَتَوَضَّأْ وُضُوءَكَ لِلصَّلَاةِ فَإِذَا نَضَحْتَ الْمَاءَ فَاغْتَسِلْ
