I prepared water for the Prophet ﷺ to bathe from major ritual impurity. He tipped the vessel with his left hand over his right and washed his palms. Then he put his hand into the vessel and poured water over his private parts, after which he rubbed his hand against the wall, or the ground. Then he rinsed his mouth and nose, washed his face and forearms, and poured water over his head three times. Next he poured water over the rest of his body, then moved aside and washed his feet.
حدثنا هناد حدثنا وكيع عن الأعمش عن سالم بن أبي الجعد عن كريب عن ابن عباس
وضعت للنبي ﷺ غسلا فاغتسل من الجنابة فأكفأ الإناء بشماله على يمينه فغسل كفيه ثم أدخل يده في الإناء فأفاض على فرجه ثم دلك بيده الحائط أو الأرض ثم مضمض واستنشق وغسل وجهه وذراعيه ثم أفاض على رأسه ثلاثا ثم أفاض على سائر جسده ثم تنحى فغسل رجليه
