Muhammad ibn ʿAli, Yahya ibn Saʿid, Zakariyya—known as Khayyāṭ al-Sunnah (“the tailor of the Sunnah”)—and many others also narrated from him.

Al-Nasaʾi judged him reliable.

ʿAbd Allah ibn Jaʿfar ibn Khāqān said: “I asked Ibrahim ibn Saʿid al-Jawhari about a hadith traced back to Abu Bakr al-Ṣiddiq. He said to his maid-servant, ‘Bring me the twenty-third fascicle of the Musnad of Abu Bakr.’

“I remarked, ‘There are not even fifty sound hadith attributed to Abu Bakr; whence come twenty-three fascicles?’

“He replied, ‘Any hadith for which I do not possess one hundred independent chains leaves me feeling like an orphan in that matter.’ (1)

Al-Khatib said: “He was trustworthy, firmly grounded, prolific, and the compiler of the Musnad.” (2)

Ibrahim ibn ʿAbd Allah related: “His father Saʿid was reliable, dignified, and noble. He performed the pilgrimage once, and four hundred people accompanied him—among them Hushaym and Ismaʿil ibn ʿAyyash; I was one of them as well.” (3)

Ahmad ibn Kamil al-Qadi said: “ʿAli ibn al-Hasan al-Najjar narrated to me, al-Ṣaghāni informed us, and Ibrahim ibn Saʿid al-Jawhari said:

‘I saw a boy, four years old, who had been brought before al-Maʾmun. He had already recited the Qur’an and engaged in rational inquiry, yet whenever he became hungry he would cry.’”

Abu Muhammad ibn al-Labbān said: “I memorized the Qur’an when I was five years old.”

I—[the author]—say: The man is trustworthy, a ḥāfiẓ, and Ḥajjāj ibn al-Shāʿir criticized him without any justification.
