وَعَن عَليّ
قَالَ: كُنْتُ رَجُلًا مَذَّاءً فَكُنْتُ أَسْتَحْيِي أَنْ أَسْأَلَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِمَكَانِ ابْنَتِهِ فَأَمَرْتُ الْمِقْدَادَ فَسَأَلَهُ فَقَالَ: «يَغْسِلُ ذَكَرَهُ وَيتَوَضَّأ»
My prostatic fluid flowed readily, and I was ashamed to consult the Prophet (sallallahu alayhi wa sallam) because of the position of his daughter so I gave orders to al-Miqdad to consult him, and the Prophet (sallallahu alayhi wa sallam) said, “He must wash his penis and perform ablution.”
