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
‘A'isha said that the Prophet (ﷺ) used to bathe for four reasons: after seminal defilement, on Friday, after being cupped, and after washing the dead. Abu Dawud transmitted it.
