Shall I not inform you of the wudu of the Messenger of Allah ﷺ? Then he performed wudu washing each part once.
حدثنا مسدد حدثنا يحيى عن سفيان حدثني زيد بن أسلم عن عطاء بن يسار
ألا أخبركم بوضوء رسول الله ﷺ فتوضأ مرة مرة
Bukhari narrated it in the Wudu chapter, "Performing Wudu Once," hadith no. 157, from the hadith of Sufyan Thawri through this route. Tirmidhi also narrated it, hadith no. 42, as did Nasai, hadith no. 80, and Ibn Majah, hadith no. 411.
