Khalid bin 'Abdullah al-Tahan خالد بن عبد الله بن عبد الرحمن الطحان · The Book of Ghusl and Tayammum

It was narrated from 'Aishah that the Messenger of Allah (ﷺ) used to perform Ghusl, he and I from a single vessel, both of us scooping water from it.

"As for me, I pour water on my head three times."
