It was narrated that Maimunah said:

"The Messenger of Allah (ﷺ) performed Wudu' as for prayer, but did not wash his feet, and he washed his private part and whatever had got onto it, then he poured water over himself, then he moved his feet and washed them." She said: "This is Ghusl from Janabah."

أَخْبَرَنَا مُحَمَّدُ بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنِ الأَعْمَشِ، عَنْ سَالِمٍ، عَنْ كُرَيْبٍ، عَنِ ابْنِ عَبَّاسٍ، عَنْ مَيْمُونَةَ، قَالَتْ تَوَضَّأَ رَسُولُ اللَّهِ صلى الله عليه وسلم وُضُوءَهُ لِلصَّلاَةِ غَيْرَ رِجْلَيْهِ وَغَسَلَ فَرْجَهُ وَمَا أَصَابَهُ ثُمَّ أَفَاضَ عَلَيْهِ الْمَاءَ ثُمَّ نَحَّى رِجْلَيْهِ فَغَسَلَهُمَا ‏‏.‏‏ قَالَتْ هَذِهِ غِسْلَةٌ لِلْجَنَابَةِ ‏‏.‏‏
