وَعَن عَلِيٍّ قَالَ: سَأَلَتْ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ الْمَذْيِ فَقَالَ: «مِنَ الْمَذْيِ الْوُضُوءُ وَمِنَ الْمَنِيِّ الْغسْل» . رَوَاهُ التِّرْمِذِيّ
‘Ali said: I asked the Prophet about prostatic fluid and he replied, “For prostatic fluid ablution is necessary, but for seminal emission washing.” Tirmidhi transmitted it.
