حَدَّثَنَا خَلَفٌ حَدَّثَنَا أَبُو جَعْفَرٍ يَعْنِي الرَّازِيَّ وَخَالِدٌ يَعْنِي الطَّحَّانَ عَنْ يَزِيدَ بْنِ أَبِي زِيَادٍ عَنْ عَبْدِ الرَّحْمَنِ ابْنِ أَبِي لَيْلَى عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ رَضِيَ اللَّهُ عَنْهُ قَالَ كُنْتُ رَجُلًا مَذَّاءً فَسَأَلْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ أَمَّا الْمَنِيُّ فَفِيهِ الْغُسْلُ وَأَمَّا الْمَذْيُ فَفِيهِ الْوُضُوءُ
مسند امام احمد بن حنبل · Hadith 662
It was narrated that 'Ali (RA) said: I was a man who emitted a great deal of wadhi (prostatic fluid). I asked the Messenger of Allah (PBUH) (about that) and he said: "As for mani (semen), ghusl is due for it; as for niiidhi (prostatic fluid), wudoo' is due for it.”
