Bathing (Ghusl)
5/9. Chapter:
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?
Sahih Bukhari
حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا اغْتَسَلَ مِنَ الْجَنَابَةِ غَسَلَ يَدَهُ.
Narrated `Aisha: Whenever Allah's Messenger (ﷺ) took a bath of Janaba, he washed his hands first.
