ʿAli b. Abū Ṭālib said: I sent al-Miqdād b. al-Aswad to the Messenger of Allah ﷺ to ask him about the madhī (pre-seminal fluid) that comes out of a man: how should he deal with it? The Messenger of Allah ﷺ said: "Do wuḍū and sprinkle water on your private parts.”
عَلِيُّ بْنُ أَبِي طَالِبٍ أَرْسَلْنَا الْمِقْدَادَ بْنَ الْأَسْوَدِ إِلَى رَسُولِ اللهِ ﷺ فَسَأَلَهُ عَنِ الْمَذْيِ يَخْرُجُ مِنَ الْإِنْسَانِ كَيْفَ يَفعَلُ؟ قَالَ رَسُولُ اللهِ ﷺ «تَوَضَّأْ وَانْضَحْ فَرْجَكَ»
