He saw Uthman bin Affan sit at the second door of the Messenger of Allah's ﷺ mosque. He called for a shoulder of meat and gnawed it clean, then he stood and prayed without performing ablution. He then said, "I sat where the Prophet ﷺ sat, ate what the Prophet ﷺ ate, and did what the Prophet ﷺ did."
حدثنا عبد الله بن بكر حدثنا حميد الطويل
أنه رأى عثمان بن عفان رضي الله عنه جلس على الباب الثاني من مسجد رسول الله ﷺ فدعا بكتف فتعرقها ثم قام فصلى ولم يتوضأ ثم قال جلست مجلس النبي ﷺ وأكلت ما أكل النبي ﷺ وصنعت ما صنع النبي ﷺ

Haythami mentioned it in Majma al-Zawaid 1/151 and attributed it to Ahmad, saying, "The men of Ahmad's chain are trustworthy," which is a misleading laxity, for he means the other, connected hadith, which has a different wording. "Taarraqaha" means he took the meat off it with his teeth, and "al-arq," with a fatha on the ain and a sakin on the ra, is the bone when most of the meat has been taken off it.
