In Fath al-Malik Al-A'li, about the authenticity of hadith of Bab al-Ilm Ali (Maghrebi, page 164), it is stated as below:

Hafiz Suyuti in Jami' al-Kabir says: It was quite some time that my mind was preoccupied about the mode of chain of transmission of this hadith until I concluded that it is “Hasan” (i.e., acceptable hadith). Later, when coincidentally, I came across Ibn Jarir’s rectification regarding narration of hadith from Ali from the book Tahdhib al-Athar together with Hakem Naishabouri’s rectification with respect to narration of this hadith from Ibn Abbas, I took recourse to “Istikhāra” (literally it means “to seek that which is good” and is a done for example, by selecting lines or passages from the Quran) until I became certain and promoted the order of hadith from “Hasan” to “Sahih” (i.e., genuine hadith). *

Refer also to the Book of Manaqib Sayedna Ali (Aini, p. 25) and al-Mustadrak ala al-Sahihayn (Hakim Nishapuri, V. 3, page 126).

In Jam'i as-Sahih (V.5, page 301), Tirmidhi narrates from Ali (a.s.) that the Messenger of Allah (s.a.w.a.) said, "I am the house of wisdom and Ali is its door."

Also Ibn Asaker in Tarikh Madinah-Damishq (V. 42, page 378) and Abu Na'im Esfahani in Hilyatul Auliya (V. 1, page 64) have recorded the same hadith.

And refer to the book Fath al-Malik al-Ali bi-sihhat hadith Bab Madinat al-'Ilm Ali, in which you will find substantial knowledge.

Also, Salman Farsi has narrated that the Messenger of Allah (s.a.w.a.) said: "The most knowledgeable person in my nation after me is Ali ibn Abi Talib."

Sa'eed ibn Musayb says: Among the companions of the Messenger of Allah (s.a.w.a.), the only person who made the claim of " سَلُونِی ", ("Ask me questions"), was Ali ibn Abi Talib.

Refer to Ibn Abd al-Barr, Al-Isti’ab, V.3, page 1103; Tauzeeh ul-Dalayil, page 211.

It is narrated from Sufyan who said, "No one had any debate with Ali except that Ali would defeat and overpower him with proofs and reasoning." Ibn Marduyeh Esfahani, Manaqib, page 87.
