"When he was the governor of Al-Madinah, Marwan mentioned that a man should perform Wudu' after touching his penis, if he touches it iwth his hand. I did not like that and I said: 'The one who touches it does not have to perform Wudu'.' Marwan said: 'Busrah bint Safwan told me that she heard the Messenger of Allah ﷺ mention the things for which Wudu' should be performed, and the Messenger of Allah ﷺ said: 'Wudu' should be performed after touching the penis.' 'Urwah said: 'I continued to argue with Marwan until he called one of his guards and sent him to Busrah to ask her about what Marwan had narrated, and Busrah sent word saying something like that which Marwan had narrated to me from her." (Using translation from Nasāʾī 164)
أَنَّهُ يُتَوَضَّأُ مِنْ مَسِّ الذَّكَرِ إِذَا أَفْضَى إِلَيْهِ الرَّجُلُ بِيَدِهِ فَأَنْكَرْتُ ذَلِكَ فَقُلْتُ لَا وُضُوءَ عَلَى مَنْ مَسَّهُ فَقَالَ مَرْوَانُ أَخْبَرَتْنِي بُسْرَةُ بِنْتُ صَفْوَانَ أَنَّهَا سَمِعَتْ رَسُولَ اللهِ ﷺ يَذْكُرُ مَا يُتَوَضَّأُ مِنْهُ فَقَالَ رَسُولُ اللهِ ﷺ «وَيُتَوَضَّأُ مِنْ مَسِّ الذَّكَرِ» قَالَ عُرْوَةُ «فَلَمْ أَزَلْ أُمَارِي مَرْوَانَ حَتَّى دَعَا رَجُلًا مِنْ حَرَسِهِ فَأَرْسَلَهُ إِلَى بُسْرَةَ يَسْأَلُهَا عَمَّا حَدَّثَ مِنْ ذَلِكَ فَأَرْسَلَتْ إِلَيْهِ بُسْرَةُ بِمِثْلِ الَّذِي حَدَّثَنِي عَنْهُ»
