What Invalidates Wudu' And What Does Not Invalidate Wudu' Of Madhi (Prostatic Fluid)
Sunan an-Nasai
أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، عَنْ عَطَاءٍ، عَنْ عَائِشِ بْنِ أَنَسٍ، أَنَّ عَلِيًّا، قَالَ كُنْتُ رَجُلاً مَذَّاءً فَأَمَرْتُ عَمَّارَ بْنَ يَاسِرٍ يَسْأَلُ رَسُولَ اللَّهِ صلى الله عليه وسلم مِنْ أَجْلِ ابْنَتِهِ عِنْدِي فَقَالَ " يَكْفِي مِنْ ذَلِكَ الْوُضُوءُ " .
It was narrated from 'A'ish bin Anas that 'Ali said: "I was a man who had a lot of prostatic discharge, so I told 'Ammar bin Yasir to ask the Messenger of Allah (ﷺ) (about it) because his daughter was married to me. He said: 'Wudu' is sufficient for that.'"
