Abd Khayr reported,

Ali taught us the manner of the Messenger of Allah's ﷺ ablution. The servant boy poured water over his hands until he had cleaned them. Then he put his hand into the vessel, rinsed his mouth, drew water into his nose, and washed his face three times and his forearms up to the elbows three times. Then he put his hand into the vessel, immersed it deep enough that the water covered the lower part, took it out, and wiped his other hand with it. Then he wiped his head once with both palms. Then he washed his feet up to the ankles three times. Then he scooped up a small handful of water with his palm and drank it, and said, "This is how the Messenger of Allah ﷺ performed his ablution."

حدثنا مروان حدثنا عبد الملك بن سلع الهمداني

عن عبد خير قال

علمنا علي رضي الله عنه وضوء رسول الله ﷺ وصب الغلام على يديه حتى أنقاهما ثم أدخل يده في الركوة فمضمض واستنشق وغسل وجهه ثلاثا ثلاثا وذراعيه إلى المرفقين ثلاثا ثلاثا ثم أدخل يده في الركوة فغمر أسفلها بيده ثم أخرجها فمسح بها الأخرى ثم مسح بكفيه رأسه مرة ثم غسل رجليه إلى الكعبين ثلاثا ثلاثا ثم اغترف هنية من ماء بكفه فشربه ثم قال هكذا كان رسول الله ﷺ يتوضأ
