ابن أبي ليلى (report 474; identity unresolved)

ʿAbd Allāh ibn ʿUbayd Allāh related to us: Muḥammad ibn Ṣāliḥ ibn Ḥayyān related to us: ʿAbd Allāh ibn Muḥammad related to us: Hishām ibn Mihrān related to us: Shabba ibn ʿIqāl—or ʿIqāl ibn Shabba—came to Sufyān al-Thawrī. Someone sitting with Sufyān began making room for him, but Sufyān told him, ‘Do not make room for him.’ The old man understood and said, ‘I go to Ibn Abī Laylā and he makes room for me; I go to Abū Ḥanīfa and he makes room for me. I come to you, and someone else makes room for me, but you forbid him!’ Sufyān lowered his head for a while, then raised it and said, ‘I fear that you may have occupied a position that made the Fire incumbent upon you.’
