Yahya bin Saeed Al-Qattan says: "The hadith narrated with the chain of Malik from Saeed bin Al-Musayyib is more preferable to me than (the one narrated by) Sufyan Al-Thawri from Ibrahim Al-Nakha'i."

Yahya bin Saeed Al-Qattan says: Among the community of hadith scholars, there is no one with more authentic hadiths than Malik; Malik was the Imam of hadith.

Ahmad bin Al-Hasan says: I heard Ahmad bin Hanbal say: I have not seen anyone like Yahya bin Sa'id Al-Qattan.

Ahmad bin Al-Hasan says: Ahmad bin Hanbal was asked about Waki‘ and ‘Abd al-Rahman bin Mahdi, so he said: Waki‘ bin Jarrah is greater in heart (that is, in piety, righteousness, asceticism, worship, and devotion), and ‘Abd al-Rahman bin Mahdi is an Imam.

Ali bin Al-Madini says: If I were made to swear an oath between the Rukn and Maqam Ibrahim, I could swear that I have not seen a greater scholar than Abdur Rahman bin Mahdi.

Imam Tirmidhi says: There is much discussion among the scholars regarding the narrators of hadith, and there are many narrations from the people of knowledge on this subject. We have mentioned some points briefly, so that from this the ranks of the people of knowledge and the differences and distinctions among them in memorization and precision may be deduced, and so that it may be known what are the reasons for which the people of knowledge have spoken about certain narrators.
