Sahih al-Bukhari 263
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 `Aisha:
حَدَّثَنَا أَبُو الْوَلِيدِ ، قَالَ حَدَّثَنَا شُعْبَةُ ، عَنْ أَبِي بَكْرِ بْنِ حَفْصٍ ، عَنْ عُرْوَةَ ، عَنْ عَائِشَةَ ، قَالَتْ كُنْتُ أَغْتَسِلُ أَنَا وَالنَّبِيُّ، صلى الله عليه وسلم مِنْ إِنَاءٍ وَاحِدٍ مِنْ جَنَابَةٍ. وَعَنْ عَبْدِ الرَّحْمَنِ بْنِ الْقَاسِمِ عَنْ أَبِيهِ عَنْ عَائِشَةَ مِثْلَهُ .
The Prophet (ﷺ) and I used to take a bath from a single pot of water after Janaba.
