حَدَّثَنَا مُسَدَّدٌ، وَقُتَيْبَةُ بْنُ سَعِيدٍ، قَالاَ حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي سَلَمَةَ، عَنْ عَائِشَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَإِذَا أَرَادَ أَنْ يَنَامَ وَهُوَ جُنُبٌ تَوَضَّأَ وُضُوءَهُ لِلصَّلاَةِ ‏.‏
Translation
‘A’ishah reported

Musaddad and Qutaybah ibn Sa'id narrated to us, saying: Sufyan narrated to us, from al-Zuhri, from Abu Salamah, from 'A'ishah, that when the Prophet, may Allah bless him and grant him peace, intended to sleep while he was in a state of janabah (major ritual impurity), he would perform ablution like his ablution for prayer.
