‘Urwah said :

‘Ali b abi Talib said to al-miqdad, and made a similar statement as above. Al-Miqdad asked him (the prophet). The prophet (ﷺ) said: he should wash his penis and testicles. Abu Dawud said : The tradition has been narrators by al-Thawri and a group of narrators from Hisham on the authority of his father from al-Miqdad, from ‘Ali reporting from the prophet (ﷺ).

حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ عُرْوَةَ، أَنَّ عَلِيَّ بْنَ أَبِي طَالِبٍ، قَالَ لِلْمِقْدَادِ وَذَكَرَ نَحْوَ هَذَا قَالَ فَسَأَلَهُ الْمِقْدَادُ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ لِيَغْسِلْ ذَكَرَهُ وَأُنْثَيَيْهِ ‏"‏ ‏.‏ قَالَ أَبُو دَاوُدَ وَرَوَاهُ الثَّوْرِيُّ وَجَمَاعَةٌ عَنْ هِشَامٍ عَنْ أَبِيهِ عَنْ عَلِيٍّ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ فِيهِ ‏:‏ ‏"‏ وَالأُنْثَيَيْنِ ‏"‏ ‏.‏
