for you have learned that this addition is not found in al-Bukhari’s Sahih. Al-Hafiz explicitly stated this in Fath al-Bari (11/142).

Sufyan al-Thawri corroborated Sufyan ibn ‘Uyaynah in transmitting it. Al-Bukhari recorded it (4392): Abu Nu‘aym narrated to us: Sufyan narrated to us, from Ibn Dhakwan, in an abbreviated form of the report. Ibn Dhakwan’s name was ‘Abdullah, and he was Abu al-Zinad.

This was the practice of the righteous predecessors, as you may see in Musannaf Ibn Abi Shaybah (8/223). Ibn Abi Shaybah, Muslim, ‘Abd al-Razzaq, and al-Humaydi narrated in the aforementioned hadith of Anas that, when the Prophet, may Allah bless him and grant him peace, drank, a Bedouin was on his right, Abu Bakr was on his left, and ‘Umar
