Abu Ahmad ibn Adi al-Jurjani: One of the Hadith preservers, especially for the Hajj narrations, and among those famous for his knowledge. Al-Nasa'i used to deny his hadiths, although he is among the Hadith scholars famous for their knowledge.
Abu al-Faraj ibn al-Jawzi: Ahmad and Abu Nu'aym praised him, and al-Bukhari narrated from him, so his absolute weakening should not be considered.
Abu Ja'far al-'Uqayli: Imam, Trustworthy
Abu Hatim al-Razi: Trustworthy
Abu Hatim ibn Hibban al-Busti: What al-Nasa'i narrated from Yahya ibn Ma'in regarding Ahmad ibn Salih is a delusion.
Abu Sa'id ibn Yunus al-Masri: He was a Hadith preserver, and once said: He had no flaw other than pride.
Abu Nu'aym al-Fadl ibn Dukin: No one more knowledgeable in the Hadith of the people of Hijaz came to us than this young man.
Abu Ya'la al-Khalili: The Hadith scholars agreed that al-Nasa'i's statement about him was prejudiced.
Ahmad ibn Hanbal: He used to consider him upright.
Ahmad ibn Shu'ayb al-Nasa'i: He is neither trustworthy nor reliable, and al-Khatib narrated in his history that he said: By Allah, he was not with us as Ibn Ma'in said about him, and he had no flaw other than pride.
Ahmad ibn Salih al-Jili: Trustworthy, follower of the Sunnah
Ibn Hajar al-'Asqalani: Trustworthy, preserver. Once: One of the imams of Hadith, preservers, combining Fiqh and Hadith. Al-Nasa'i was prejudiced against him, and Yahya ibn Ma'in's criticism of him is not valid.
Al-Dhahabi: The Hadith preserver of the lands of Egypt and its scholar. Trustworthy, like a mountain. Ibn Ma'in's statement about him should not be considered, nor al-Nasa'i's statement that he is not trustworthy. Al-Bukhari cited him as evidence, but there was some rigidity and harshness in him, may Allah forgive him. He was a sheikh in knowledge, precise, and once: cited as evidence, the trustworthy Hadith preserver. Al-Nasa'i attacked him without justification. Ibn Ma'in spoke about him.
Al-Mizzi: He was one of the prominent Hadith preservers and the mentioned imams.
Salih ibn Muhammad Jazara: There was no one in Egypt who was better in Hadith and memorization than Ahmad ibn Salih. He understood Hadith and was good at taking it.
Ali ibn al-Madini: He used to consider him upright.
Muhammad ibn Isma'il al-Bukhari: Trustworthy, truthful. I have not seen anyone criticize him with justification. Ahmad, Ali ibn Numayr, and others considered him upright.
Muhammad ibn Abd al-Rahman al-Ghazal: He was one of the Hadith preservers, conscious, a leader in Hadith science and its chains of narration.
Muhammad ibn Abdullah ibn Numayr: If you cross the Euphrates, there is no one like him.
Muslim ibn al-Qasim al-Andalusi: People are unanimous about the trustworthiness of Ahmad ibn Salih for his knowledge, goodness, and virtue. He would not narrate Hadith to anyone until two Muslims testified before him that he was of good character and justice. Al-Nasa'i came to hear from him, entered without permission, and did not bring two people to testify to his justice. When he saw him in his gathering, he denied him and ordered him to be expelled. So al-Nasa'i weakened him for this.
Yahya ibn Ma'in: He considered him trustworthy. As for his statement that he is a liar who philosophizes, I saw him make a mistake in the Jami' in Egypt, it is a delusion.
Ya'qub ibn Sufyan al-Faswi: An authority
