al-Ḥārith ibn Sulaym ibn ʿUbayd ibn Sufyān—ḥāfiẓ, authoritative proof, and imām—Abū ʿUthmān al-Hujaymī, the Basran.
The Hujaym clan belongs to Banū al-ʿAnbar, a branch of Tamīm.
He narrated from Hishām ibn ʿUrwah, Ḥumayd al-Ṭawīl, Ayyūb, Ashʿath ibn ʿAbd al-Malik al-Ḥumrānī, ʿAbd al-Malik ibn Abī Sulaymān, ʿAwf, Ibn ʿAwn, Bishr ibn Ṣuḥār, ʿAbd al-Ḥamīd ibn Jaʿfar, Ibn Abī ʿArūbah, Shuʿbah, Ibn ʿAjlān, Ḥusayn al-Muʿallim, and many others.
He was a storehouse of knowledge—highly meticulous, admirably precise, and steadfast in his religion.
Those who transmitted from him include Shuʿbah (despite being one of his own teachers), Musaddad, Aḥmad ibn Ḥanbal, Ibn al-Madīnī, ʿAmrū ibn ʿAlī, Isḥāq ibn Rāhawayh, Ḥumayd ibn Masʿadah, Muḥammad ibn al-Muthannā, Naṣr ibn ʿAlī, Aḥmad ibn al-Miqdām, al-Ḥasan ibn Qazaʿah, and al-Ḥasan ibn ʿArafah—the last man to narrate from him.
Muḥammad ibn ʿAbd Allah ibn ʿAmmār related that Yaḥyā al-Qaṭṭān said, “I have never seen anyone better than Sufyān and Khālid ibn al-Ḥārith.”
Al-Athram reports from Aḥmad ibn Ḥanbal: “In Basra, the final word on verification rests with him”—meaning Khālid.
Al-Marwadhī likewise transmits from Aḥmad: “Khālid ibn al-Ḥārith would convey a ḥadīth exactly as he heard it, and Ibn Mahdī would also convey a ḥadīth exactly as he heard it….”
