ذِكْرُ الْبَيَانِ بِأَنَّ قَوْلَهُ ﷺ «فَلْيَنْضَحْ فَرْجَهُ» أَرَادَ بِهِ: فَلْيَغْسِلْ ذَكَرَهُ
I was a man who emitted a great deal of madhi, so I asked the Prophet ﷺ and he said: “If you see madhi then do wudoo’ and wash your private part, and if you see water gushing then do ghusl.ʿ I [the narrator] mentioned that to Sufyan and he said: I heard that from Rukain. Muʿawiyah and ibn Abi Bukair told us: Zaʿidah told us: ar-Rukain bin ar-Rabee bin ‘Ameelah al-Fazari told us... And he mentioned a similar report, and they said: water gushing. And Ibn Abu Bukair told us: Zaʿidah told us, and he also said, gushing. (Using translation from Aḥmad 1028)
كُنْتُ رَجُلًا مَذَّاءً فَسَأَلْتُ النَّبِيَّ ﷺ فَقَالَ «إِذَا رَأَيْتَ الْمَذْيَ فَاغْسِلْ ذَكَرَكَ وَإِذَا رَأَيْتَ الْمَاءَ فَاغْتَسِلْ»
