Some have maintained that, despite his fame, scarcely any major authority transmitted from him; yet in our view the facts are not as they claim.

The narrators who preserved the greatest number of his reports are: Ismāʿīl ibn Abī Khālid—trustworthy and firmly grounded—and Bayān ibn Bishr—likewise trustworthy and firmly grounded—together with a number of others he named (1).

ʿAbd al-Raḥmān ibn Khirrāsh said, “He is a distinguished Kufan. Among the Successors, no one narrated from the Ten [Companions promised Paradise] except Qays ibn Abī Ḥāzim.” (2)

Muʿāwiyah ibn Ṣāliḥ related from Yaḥyā ibn Maʿīn: “Qays ibn Abī Ḥāzim is more reliable than al-Zuhrī and than al-Sāʾib ibn Yazīd.” (3)

Aḥmad ibn Abī Khaythamah likewise reported from Ibn Maʿīn the judgment: “Trustworthy.”

Several other critics also deemed him reliable.

ʿAlī ibn al-Madīnī reported that Yaḥyā ibn Saʿīd said to him, “Qays ibn Abī Ḥāzim’s ḥadith are objectionable (munkar).”

He then cited a number of such objectionable reports, including the ḥadith of “the Dogs of al-Hawʾab” (4).

Abū Saʿīd al-Ashajj said: “I heard Abū Khālid al-Aḥmar say to Ibn Numayr, ‘Abū Hishām, do you not recall Ismāʿīl ibn Abī Khālid when he would say, “Qays ibn Abī Ḥāzim narrated to us”?’”
