Shall I not inform you of the wudu of the Messenger of Allah ﷺ? Then he performed wudu washing each part once.
أخبرنا محمد بن المثنى قال حدثنا يحيى عن سفيان قال حدثنا زيد بن أسلم عن عطاء بن يسار
ألا أخبركم بوضوء رسول الله ﷺ فتوضأ مرة مرة
Bukhari also narrated it in the Book of Wudu, Chapter on Performing Wudu Once, hadith (157), from the hadith of Sufyan Thawri, through the same route, and it is also in al-Kubra, hadith (85).
