Abū al-Faḍl Aḥmad ibn Hibat Allah related to us—in the reading I presented to him in 696 AH—from ʿAbd al-Muʿizz ibn Muḥammad al-Harawī. He was informed by Tamīm ibn Abī Saʿīd al-Qaṣṣār; he was informed by Muḥammad ibn ʿAbd al-Raḥmān in 449 AH; he was informed by the ḥāfiẓ Muḥammad ibn Muḥammad al-Naysābūrī; he was informed by Abū Bakr Muḥammad ibn Isḥāq; ʿAlī ibn Ḥujr narrated to us; ʿAbd al-ʿAzīz ibn Ḥuṣayn narrated from Abū Umayyah, who reported that Ḥabīb told him, on the authority of Zirr ibn Ḥubaysh:
