Al-Muttalib bin 'Abdullah bin Hantab (narrated) that 'Abdullah bin 'Umar performed Wudu', washing each part of the body three times, and he attributed that to the Prophet ﷺ. (Using translation from Nasāʾī 81)
أَنَّ ابْنَ عُمَرَ كَانَ يَتَوَضَّأُ ثَلَاثًا ثَلَاثًا وَيُسْنِدُ ذَلِكَ إِلَى رَسُولِ اللهِ ﷺ
