حَدَّثَنَا عَبِيدَةُ بْنُ حُمَيْدٍ حَدَّثَنِي يَزِيدُ بْنُ أَبِي زِيَادٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى عَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ قَالَ كُنْتُ رَجُلًا مَذَّاءً فَسَأَلْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَوْ سُئِلَ عَنْ ذَلِكَ فَقَالَ فِي الْمَذْيِ الْوُضُوءُ وَفِي الْمَنِيِّ الْغُسْلُ
مسند امام احمد بن حنبل · Hadith 869
It was narrated that 'Ali (RA) said: I was a man who emitted a great deal of madhi, so I asked the Prophet (PBUH) or he was asked about that, and he said: "For fnadhi do wudoo ' and for mani do ghusl."
