Arabic hadith text
وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: كَانَ يَغْتَسِلُ مِنْ أَربع: من الْجَنَابَة وَمن يَوْم الْجُمُعَة وَمن الْحجام وَمن غسل الْمَيِّت. رَوَاهُ أَبُو دَاوُد
Translation
‘A'isha said that the Prophet used to bathe for four reasons
after seminal defilement, on Friday, after being cupped, and after washing the dead. Abu Dawud transmitted it.
