His scholarly status:
1 – Learning knowledge in childhood:
Al-Khallal said: I heard Harb al-Kirmani say: Abu Abdillah came out to read to me. He said: I think he said: the book "Al-Ashriba" (The Drinks). He said: Then Abdullah, his son, came and said: "Did you not promise me that you would read to me?" – and he was at that time a boy –. He said: So Abu Abdillah began urging him to be patient. He said: So Abdullah wept. He said: Then Abu Abdillah said to me: "Be patient with me until I enter and read to him." He said: So Abu Abdillah entered, read to him, and came out.
2 – Imam Ahmad was eager to teach him and read to him:
Al-Khallal mentioned him, saying: Abu Abdillah used to read to him often, and sometimes Salih was absent, so he would say to him: "Salih is busy with his family, so read to me."
But he would not do so.
He said: When that became frequent upon him, and he knew his heavy busyness and absence from listening, my father used to read to me when Salih was absent and leave him.
3 – Imam Ahmad, may Allah have mercy on him, used to forbid him from reading to the people of innovation:
Abu Ja'far al-Uqayli, may Allah have mercy on him, said in "Al-Du'afa" (3/225): I said to Abdullah ibn Ahmad ibn Hanbal: "Why did you not write from Ali ibn al-Ja'd?" He said: "My father forbade me to go to him; for it reached him about him that he spoke ill of the Companions of the Prophet ﷺ."
Praise of the scholars for him:
Abbas al-Duri said: I was with Ahmad ibn Hanbal one day, and his son Abdullah entered upon us. Ahmad said to me: "O Abbas, Abu Abd al-Rahman has indeed retained a great deal of knowledge."
And Isma'il ibn Ali al-Khutabi said: It reached me from Abu Zur'a that he said: Ahmad ibn Hanbal said to me: "My son Abdullah is fortunate in the knowledge of Hadith – or in memorizing Hadith –, he hardly reviews with me except that which I do not memorize."
And Abu al-Husayn ibn al-Munadi said: There was no one in the world who narrated more from his father than him; because he heard "Al-Musnad", which is thirty thousand [narrations], and "Al-Tafsir", which is one hundred and twenty thousand – he heard eighty thousand from him, and the rest via Wijadah [finding written records] –, and he heard "Al-Nasikh wa al-Mansukh", "Al-Tarikh", "Hadith Shu'ba", "Al-Muqaddam wa al-Mu'akhkhar fi Kitab Allah", "Jawabat al-Qur'an", "Al-Manasik al-Kabir", "Al-Saghir", and other compilations and narrations of the teachers.

He said: And we continue to see the greatest of our teachers testifying to his knowledge of narrators (Rijal), defects of Hadith ('Ilal), names and patronymics (Kunas), and perseverance in seeking Hadith in Iraq and elsewhere, and mentioning from their predecessors the acknowledgment of that for him, to the extent that some of them went to excess in praising his knowledge and his having heard more Hadith than his father.
And Abu Ahmad ibn 'Adi said: He gained nobility through his father, and he himself holds a status in knowledge. So he revived his father's knowledge from his "Musnad", which his father read to him specifically before reading it to anyone else. And among what he asked his father about the Hadith narrators and which he informed him about was that which no one else asked him. And he did not write from anyone except those his father commanded him to write from.
And Badr ibn Abi Badr al-Baghdadi said: Abdullah ibn Ahmad is a critical scholar (Jahbadh), son of a critical scholar (Jahbadh).
And Abu Bakr al-Khatib said: He was trustworthy (Thiqa), reliable (Thabat), and understanding (Fahim).
And Adh-Dhahabi said: The Imam, the Hafiz, the critic, the Hadith scholar of Baghdad, Abu Abd al-Rahman, son of the Shaykh of the era Abu Abdillah al-Dhuhli al-Shaybani, al-Marwazi, then al-Baghdadi.
And he said: And he was chaste/guarded, religious, truthful, a man of Hadith and adherence [to Sunnah], insightful regarding narrators, he did not enter into anything other than Hadith, and he has many clear additions (Ziyadat) in his father's "Musnad" from the high-ranking chains of his scholars.
