Habib bin Salih said: Among the people, I have never feared anyone more than Khalid bin Ma'dan. (That is, due to his knowledge, there was always an awe over me.)

Mughira bin Muqsim said: We used to fear Imam Ibrahim Nakha'i like an amir or governor.

Ayyub (as-Sakhtiyani) said: Sa'id bin Jubayr narrated a hadith one day, so I stood up and requested: Please repeat it twice. He replied: I do not milk (the animal) every moment, nor do I drink (every moment).

Ata bin As-Sa'ib said: Abu Abdur Rahman disliked narrating hadith while walking on the road.

Habib bin Thabit said that we were with Saeed bin Jubair, may Allah have mercy on him, when he narrated a hadith. So a man asked him: Did someone narrate this hadith to you? Or from whom did you hear it? At this, Saeed, may Allah have mercy on him, became upset and forbade us from speaking to that man until he got up and left.

Abu Salamah said: I wish I had kept the company of Sayyiduna Ibn Abbas (may Allah be pleased with them both), so I would have acquired a large portion of his knowledge.

Umm Abdullah bint Khalid said: I have not seen anyone who honored knowledge more than my father.

Sulaiman bin Musa said: I said to Imam Tawus (may Allah have mercy on him): So-and-so narrated such-and-such to me. He said: Your narrators (of hadith) are trustworthy, so take their narration.

Sa’d bin Ibrahim said: Only trustworthy narrators report hadith from the Messenger of Allah, peace and blessings be upon him.

Imam Muhammad bin Sirin, may Allah have mercy on him, said: In the beginning, people did not ask about the chain of narration, then they started asking (i.e., they began to inquire about who the narrator is and what he is like). If the narrator was a follower of the Sunnah, they would accept the hadith from him, and if he was not a follower of the Sunnah, they would not accept the hadith from him. Imam Darimi said: I do not think that Jarir heard this from Asim.
