(10) باب الْقَدْرِ الْمُسْتَحَبِّ مِنَ الْمَاءِ فِي غُسْلِ الْجَنَابَةِ وَغُسْلِ الرَّجُلِ وَالْمَرْأَةِ فِي إِنَاءٍ وَاحِدٍ فِي حَالَةٍ وَاحِدَةٍ وَغُسْلِ أَحَدِهِمَا بِفَضْلِ الآخَرِ
Salama b. Abd al-Rahman narrated it on the authority of A'isha that when the Messenger of Allah (ﷺ) took a bath, he started from the right hand and poured water over it and washed it, and then poured water on the impurity with the right band and washed it away with the help of the left hand. and after having removed it, he poured water on his head. A'isha said:
I and the Messenger of Allah (ﷺ) took a bath from the same vessel, after sexual intercourse.
