Ata bin Abi Rabah says: We left from Jabir bin Abdullah (may Allah be pleased with them both) and discussed his hadiths, and Abu Az-Zubair was the one who remembered these hadiths the most.

Abu Az-Zubair says that Ata bin Abi Rabah used to put me forward before Jabir bin Abdullah (may Allah be pleased with them both), so that I could memorize hadith for him.

Ayyub Sakhtiyani says: Abu al-Zubair narrated a hadith to us, and Abu al-Zubair, and Abu al-Zubair, and Abu al-Zubair—Sufyan al-Thawri was holding his hand and saying this. Al-Tirmidhi says: Sufyan ibn ‘Uyaynah wanted to indicate by this statement that Abu al-Zubair is strong and firm in memorizing and narrating hadith.

It is narrated from Abdullah bin Mubarak that Sufyan Thawri used to say: Abdul Malik bin Abi Sulayman is the scale of knowledge.

Ali bin Al-Madini says: I asked Yahya bin Sa’id Al-Qattan about Hakim bin Jubair, so he said: Shu’bah abandoned narrating from him because of the hadith about charity, that is, the hadith of Ibn Mas’ud that the Prophet ( صلی اللہ علیہ وسلم ) said:“Whoever asks (for charity) while he possesses wealth that makes him independent of others, then on the Day of Resurrection he will come with scratches on his face.”It was asked: O Messenger of Allah! What makes a person independent of others? He said:“Fifty dirhams (of silver) or its equivalent in gold.”

It is narrated from Ali bin Al-Madini that Yahya bin Saeed Al-Qattan says: Sufyan Thawri and Zaidah narrated from Hakeem bin Jubair.

And Ali bin Al-Madini says that, according to Yahya bin Saeed Al-Qattan, there is no problem in the hadith of Hakeem bin Jubair.

Tirmidhi says: Mahmood bin Ghailan narrated to us, from Yahya bin Adam, Yahya narrated from Sufyan Thawri, he says that Hakeem bin Jubair narrated the hadith regarding charity.

Yahya bin Adam says: Abdullah bin Uthman, a student of Shu’bah, said to Sufyan Thawri: If the hadith about charity had been narrated by someone other than Hakim bin Jubair, what would be the ruling? Sufyan Thawri replied: What happened to Hakim that Shu’bah did not narrate from him? Abdullah bin Uthman said: Yes! (It is so, Shu’bah did not narrate from Hakim.) So Sufyan Thawri said: I heard Zubayd narrate this hadith from Muhammad bin Abdur Rahman bin Yazid.

Imam Tirmidhi says: In this book, whenever we have called a hadith "Hasan," we mean that its chain of narration is "Hasan."
