Translation
Narrated Abdullah ibn Amr ibn al-'As

Musaddad narrated to us: Abu Awanah narrated to us, from Musa ibn Abi Aishah, from Amr ibn Shu'ayb, from his father, from his grandfather, that a man came to the Prophet (ﷺ) and said: O Messenger of Allah, how is purification?

He then called for water in a vessel and washed his hands three times, then washed his face three times, then washed his forearms three times, then wiped his head, inserting his two index fingers into his ears, and wiping the backs of his ears with his thumbs and the insides of his ears with his index fingers. Then he washed his feet three times, and said: This is how ablution is. Whoever exceeds this or falls short of it has done wrong and transgressed - or transgressed and done wrong.
