Abu Ahmad ibn Adi al-Jurjani: He is truthful, trustworthy, and there is nothing wrong with him. It is sufficient for his truthfulness that Malik narrated from him, for Malik would not narrate except from a trustworthy person. I do not know of any of the trustworthy narrators who differed from Abu az-Zubayr except that they wrote from him. He himself is trustworthy, except that some weak narrators narrate from him, so that is from the side of the weak narrator, and not from his side. Abu az-Zubayr narrates sound hadiths.
Abu al-Hasan ibn al-Qattan al-Fasi: Whenever he said, 'I heard Jabir,' it is considered hearing (Sima'). And whenever he said, 'On the authority of Jabir,' there is a disconnection between them (Tadlis). Once, he practiced Tadlis, but when it was pointed out to him, he stopped.
Abu Hatim al-Razi: His hadith is written but not used as evidence. He is more preferable to me than Abu Sufyan Talha ibn Nafi'.
Abu Hatim ibn Hibban al-Busti: He authenticated him.
Abu Zar'a al-Razi: He was asked, 'Is his hadith used as evidence?' He said: 'Only the hadith of trustworthy narrators is used as evidence.'
Abu 'Abd Allah al-Hakim al-Naysaburi: Shu'bah does not have any evidence against him except that he wore black clothes and boasted about his presence with a scholar.

Ahmad ibn Shu'ayb al-Nasa'i: Trustworthy.
Ahmad ibn Salih al-Jili: Trustworthy.
Ayyub ibn Abi Tamima al-Sakhtiyani: It is as if he considers him weak.
Ibn Hajar al-'Asqalani: Truthful, but he practices Tadlis. And once: One of the Tabi'een, famous, authenticated by the majority, and weakened by some due to excessive Tadlis and other reasons. Al-Bukhari did not narrate from him except for one hadith.
Ibn 'Abd al-Barr al-Andalusi: Trustworthy, حافظ (preserver).
Al-Dhahabi: A حافظ (preserver), trustworthy, and he practiced Tadlis. A scholar of vast knowledge. He said in the Tadhhib: 'He was one of the Imams of the Tabi'een.'
Al-Layth ibn Sa'd al-Masri: He criticized him.
Zakariya ibn Yahya al-Saji: Truthful, an authority in legal rulings.
Sabit ibn al-'Ajami: Known for Tadlis.
Sufyan ibn 'Uyaina: It is as if he considers him weak.
Shu'bah ibn al-Hajjaj: He took Hisham's book from Abu az-Zubayr and tore it apart. 'Do not write from Abu az-Zubayr, for he does not know how to pray properly.' And once: He spoke very harshly about him.
Abd al-Malik ibn 'Abd al-'Aziz ibn Jurayj: I did not think I would live to see the day when the hadith of Abu az-Zubayr would be narrated.
Ataa ibn Abi Rabah: He was the most knowledgeable of us in hadith.

Yahya ibn Ma'in: Trustworthy. And once: Reliable. And once: More preferable to me than Abu Sufyan, meaning Talha. Abu az-Zubayr did not hear from 'Abdullah ibn 'Amr nor did he see him.
Ya'qub ibn Shaybah al-Sadusi: Trustworthy, truthful. But he leans towards weakness.
Ya'la ibn 'Utayya al-'Amiri: He was the most perfect of people in intellect and the most knowledgeable of them.
