Sahih al-Bukhari 264
Sahih al-Bukhari · Book 5: Bathing (Ghusl) · Can a Junub (a person who has yet to take bath after the sexual act or wet dream) put his hands in a pot (containing water) before washing them if they are not polluted with a dirty thing except Janaba?
Narrated Anas bin Malik:
حَدَّثَنَا أَبُو الْوَلِيدِ ، قَالَ حَدَّثَنَا شُعْبَةُ ، عَنْ عَبْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ جَبْرٍ ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ، يَقُولُ كَانَ النَّبِيُّ صلى الله عليه وسلم وَالْمَرْأَةُ مِنْ نِسَائِهِ يَغْتَسِلاَنِ مِنْ إِنَاءٍ وَاحِدٍ. زَادَ مُسْلِمٌ وَوَهْبٌ عَنْ شُعْبَةَ مِنَ الْجَنَابَةِ .
The Prophet (ﷺ) and one of his wives used to take a bath from a single pot of water. (Shu`ba added to Anas' Statement "After the Janaba").
