(22) باب الْغُسْلِ مَرَّةً وَاحِدَةً
It was narrated that Maimunah, the wife of the Prophet (ﷺ), said:
"The Prophet (ﷺ) performed Ghusl from Janabah; he washed his private part then rubbed his hand on the ground or the wall, then he performed Wudu' as for prayer, then he poured water over his head and the rest of his body."
