A mistake by someone transmitting from Ibn al-Mubārak introduced Sufyān’s name.
• The version with the addition places Sufyān between Ibn al-Mubārak and ‘Abd al-Raḥmān.
• Reliable transmitters report it through Ibn al-Mubārak from ‘Abd al-Raḥmān without Sufyān.
• This particular error is attributed to a transmitter below Ibn al-Mubārak, not to Ibn al-Mubārak himself.
1. Wahm: a mistake in transmitting the report here.
