It was narrated that 'Aishah said:"When the Messenger of Allah (ﷺ0 performed Ghusl from Janabah, he would wash his hands, then perform Wudu' as for prayer, then run his fingers through his hair until he was sure the water had reached the scalp, then he would pour water over his head three times, then wash the rest of his body)
