We sent al-Miqdad b. al-Aswad to the Messenger of Allah ﷺ to ask him what must be done about prostatic fluid which flows from (the private part of) a person. The Messenger of Allah ﷺ said: Perform ablution and wash your sexual organ.
عَلِيُّ بْنُ أَبِي طَالِبٍ أَرْسَلْنَا الْمِقْدَادَ بْنَ الأَسْوَدِ إِلَى رَسُولِ اللَّهِ ﷺ فَسَأَلَهُ عَنِ الْمَذْىِ يَخْرُجُ مِنَ الإِنْسَانِ كَيْفَ يَفْعَلُ بِهِ فَقَالَ رَسُولُ اللَّهِ ﷺ تَوَضَّأْ وَانْضَحْ فَرْجَكَ
