Arabic (Original)
حَدَّثَنَا عُثْمَانُ بْنُ عُمَرَ أَنْبَأَنَا مَالِكٌ عَنْ سَالِمٍ أَبِي النَّضْرِ عَنْ سُلَيْمَانَ بْنِ يَسَارٍ عَنِ الْمِقْدَادِ بْنِ الْأَسْوَدِ أَنَّهُ سَأَلَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ الرَّجُلِ يَدْنُو مِنْ امْرَأَتِهِ فَيُمْذِي قَالَ إِذَا وَجَدَ ذَلِكَ أَحَدٌ فَلْيَنْضَحْ فَرْجَهُ قَالَ يَعْنِي يَغْسِلُهُ وَلْيَتَوَضَّأْ وُضُوءَهُ لِلصَّلَاةِ.
English Translation
Uthman ibn Umar narrated to us: Malik informed us from Salim Abu al-Nadr from Sulayman ibn Yasar from al-Miqdad ibn al-Aswad, that he asked the Messenger of Allah, peace and blessings be upon him, about a man who approaches his wife and prostatic fluid (madhy) emerges. He said: "If anyone finds that, let him sprinkle his private part" -- meaning wash it -- "and perform ablution as for prayer."
