Ayesha reported,

Aishah reported that whenever the Messenger of Allah ﷺ performed the ritual bath from major impurity, a vessel would be placed before him. He would pour water onto his hands before dipping them into the vessel. Once he had washed his hands, he would put his right hand into the vessel, then pour water with his right hand and wash his private parts with his left. When he finished, he would pour water from his right hand onto his left and wash them both. Then he would rinse his mouth and nose three times. After that, he would pour three handfuls of water over his head, then let the water flow over the rest of his body.

حدثتني عائشة رضي الله عنها

أن رسول الله ﷺ كان إذا اغتسل من الجنابة وضع له الإناء فيصب على يديه قبل أن يدخلهما الإناء حتى إذا غسل يديه أدخل يده اليمنى في الإناء ثم صب باليمنى وغسل فرجه باليسرى حتى إذا فرغ صب باليمنى على اليسرى فغسلهما ثم تمضمض واستنشق ثلاثا ثم يصب على رأسه ملء كفيه ثلاث مرات ثم يفيض على جسده
