وَعَنْ عَائِشَةَ رَضِيَ اَللَّهُ عَنْهَا
قَالَتْ: «كَانَ اَلنَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَغْتَسِلُ مِنْ أَرْبَعٍ: مِنْ اَلْجَنَابَةِ، وَيَوْمَ اَلْجُمُعَةِ، وَمِنْ اَلْحِجَامَةِ، وَمِنْ غُسْلِ اَلْمَيِّتِ»
The Messenger of Allah (sallallahu alayhi wa sallam) used to take a bath from four things; after sexual intercourse, on Fridays, after extracting blood from his body and after washing a dead body.
