(19) باب اسْتِبْرَاءِ الْبَشَرَةِ فِي الْغُسْلِ مِنَ الْجَنَابَةِ
It was narrated that 'Aishah said:
"When the Messenger of Allah (ﷺ) performed Ghusl from Janabah, he would call for something like a vessel used for milking a she-camel, then he would take (some water) in his hand and start with the right side of his head, then the left, then take (some water) in his hands and start pouring it on his head."
