The Book of Purification and its Sunnah — Hadith #239
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا عُثْمَانُ بْنُ عُمَرَ، حَدَّثَنَا مَالِكُ بْنُ أَنَسٍ، عَنْ سَالِمٍ أَبِي النَّضْرِ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، عَنِ الْمِقْدَادِ بْنِ الأَسْوَدِ، أَنَّهُ سَأَلَ النَّبِيَّ ـ صلى الله عليه وسلم ـ عَنِ الرَّجُلِ يَدْنُو مِنِ امْرَأَتِهِ فَلاَ يُنْزِلُ قَالَ
" إِذَا وَجَدَ أَحَدُكُمْ ذَلِكَ فَلْيَنْضِحْ فَرْجَهُ - يَعْنِي لِيَغْسِلْهُ - وَيَتَوَضَّأْ " .
He asked the Prophet about a man who approached his wife, but did not ejaculate. He said: “If anyone of you finds that, he should sprinkle water over his private part (meaning he must wash it) and perform ablution.”
