Usd al-Ghābah (2/372), al-Ṭabarānī in al-Muʿjam al-Kabīr (7/375–376/7235), and, through him, Abū Nuʿaym in Maʿrifat al-Ṣaḥābah [title struck out in the original], by two chains from Abū al-Mughīrah, who said: Ṣafwān ibn ʿAmr narrated to us; ʿAbd al-Raḥmān ibn Jubayr narrated to us, from Abū Ṭawīl Shaṭab al-Mamdūd:
