Abu Ahmad ibn Adi al-Jurjani: He and his narrations are fine. He narrated many Hadiths and strange things
Abu Ja'far al-'Uqayli: His Hadiths are not corroborated
Abu Hatim al-Razi: He is weak in Hadith
Abu Hatim ibn Hibban al-Busti: He used to memorize, he was among those who collected and compiled, and he relied on his memory, so he might make a mistake after a mistake. A person's mistake in something he is keen on is not a big deal unless it is excessive to the extent that he narrates from those who are not trustworthy even if he is considered trustworthy
Abu Dawud al-Sijistani: We saw in his Musnad some Hadiths that we found strange. We asked him for the original manuscripts, he refused. Then he brought them out later, and we found the Hadiths in the original manuscripts changed in a fresh handwriting. They were Mursal (narrations with a missing link in the chain) but he connected them and added to them
Abu Zur'a al-Razi: He was asked: Was he truthful? He said: This requires conditions. He said: My heart is not at peace with him
Abu 'Abd Allah al-Hakim al-Naysaburi: No one spoke about him with an argument
Abu Mas'ab al-Zuhri: He recommended writing from him
Ahmad ibn Shu'ayb al-Nasa'i: He is not reliable. And once: He is not trustworthy
Ibn Hajar al-'Asqalani: Truthful but he might make mistakes
Al-Dhahabi: The Haafidh (The Preserver)
Salih ibn Muhammad Juzra: Some people criticized him
Abbas ibn 'Abd al-'Azim al-'Anbari: He connects the chain of narration
Muhammad ibn Isma'il al-Bukhari: We did not see anything except good. He is originally truthful
Muslim ibn al-Qasim al-Andalusi: Trustworthy
Mus'ab ibn 'Abd Allah al-Zubayri: Trustworthy, reliable, a scholar of Hadith
Authors of Tahdhib al-Tahdhib: Weak but considered in corroborations and supporting narrations
Yahya ibn Ma'in: Trustworthy. And once: He is not reliable. And once: A liar, wicked, an enemy of Allah, he is criticized. It was said to him: So, is the Hadith of someone who is criticized not accepted? He said: No, the Hadith of someone who is criticized is not accepted
