Abu Hazim reported,

I was behind Abu Hurairah while he was performing ablution for prayer. He would extend his hand until it reached his armpit. I said to him, "Abu Hurairah, what is this ablution?"He replied, "Sons of Faruq, are you here? Had I known you were here, I would not have performed this ablution. I heard my beloved friend ﷺ say, 'The ornament of the believer will reach as far as the ablution reaches.'"

Muslim 586

Sahih

حدثنا قتيبة بن سعيد حدثنا خلف يعني ابن خليفة عن أبي مالك الأشجعي

عن أبي حازم قال

كنت خلف أبي هريرة وهو يتوضأ للصلاة فكان يمد يده حتى تبلغ إبطه فقلت له يا أبا هريرة ما هذا الوضوء فقال يا بني فروخ أنتم هاهنا لو علمت أنكم هاهنا ما توضأت هذا الوضوء سمعت خليلي ﷺ يقول تبلغ الحلية من المؤمن حيث يبلغ الوضوء
