ʿAlī ibn al-Madīnī was asked about him and declared him to be extremely weak.

Abū Zurʿah said: I heard Ibrāhīm ibn Mūsā. He was asked, “Why do you not relate from ʿUmar ibn Hārūn?” He answered, “People have abandoned his ḥadith.” Ibrāhīm ibn Mūsā himself said, “I wrote down a bundle of narrations from him, yet I do not transmit anything on his authority.”

Abū Isḥāq al-Jūzajānī said: “The scholars were not content with his narrations.”

Ṣāliḥ Jazrah and al-Nasāʾī both said: “His ḥadith is to be left.”

Zakariyyā al-Sājī said: “There is weakness in him.”

Abū ʿAlī al-Ḥāfiẓ said: “Abandoned.”

Al-Dāraquṭnī said: “Weak.”

Al-Tirmidhī commented: “We do not know this report except through the ḥadith of ʿUmar, and I observed that Muḥammad held a favorable opinion of him.”
