I asked ʿUthman bin ʿAffan about a person who engaged in intercourse but did no discharge. ʿUthman replied, "He should perform ablution like the one for an ordinary prayer but he must wash his penis." ʿUthman added, "I heard it from Messenger of Allah ﷺ." I asked ʿAli Az-Zubair, Talha and Ubai bin Kaʿb about it and they, too, gave the same reply. (This order was canceled later on and taking a bath became necessary for such cases).
عُثْمَانُ يَتَوَضَّأُ كَمَا يَتَوَضَّأُ لِلصَّلاَةِ وَيَغْسِلُ ذَكَرَهُ قَالَ عُثْمَانُ سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ ﷺ فَسَأَلْتُ عَنْ ذَلِكَ عَلِيًّا وَالزُّبَيْرَ وَطَلْحَةَ وَأُبَىَّ بْنَ كَعْبٍ ؓ فَأَمَرُوهُ بِذَلِكَ
