– Ibn Abi Ya'la stated in *Tabaqat al-Hanabila* (3/24): "...And he traveled to the farthest regions to collect the rulings (*masa'il*) of Ahmad, hearing them from those who heard them from Ahmad, and from those who heard them from those who heard them from Ahmad. He acquired [an abundance] of them, and preceded to what no predecessor had reached before him, and no successor caught up to after him. The senior scholars (*shuyukh*) of the *madhhab* would testify to his excellence and precedence." End quote.
– Al-Khatib al-Baghdadi stated in his *Tarikh* (6/300): "He was among those who directed his care to collecting the sciences of Ahmad bin Hanbal and seeking them out. He traveled for them, wrote them down with high and low [chains of narration] (*'aliyah wa nazilah*), and compiled them into books. Among those who adopted the *madhhab* of Ahmad, there was no one more comprehensive in doing so than him." End quote.
– Al-Dhahabi stated in *Al-Siyar* (14/297): "The Imam, the Erudite Scholar (*'allamah*), the Hadith Master (*hafiz*), the Jurist (*faqih*), the Shaykh of the Hanbalis and their scholar... He traveled to Fars, the Levant (Al-Sham), and the Peninsula (Al-Jazirah) seeking the jurisprudence (*fiqh*) of Imam Ahmad, his verdicts (*fatawa*), and his answers. He wrote from the senior and junior [scholars], even writing from his [Ahmad's] students. He gathered and preserved [abundantly]. Then, he compiled the book *Al-Jami' fi al-Fiqh* (The Comprehensive Compilation of Jurisprudence) from the words of the Imam using 'he informed us' (*akhbarana*) and 'he narrated to us' (*haddathana*), comprising twenty volumes. He compiled the book *Al-'Ilal* (Hidden Defects) concerning Ahmad in three volumes, authored the book *Al-Sunnah*, and [compiled] the utterances of Ahmad and the evidence for that from the hadiths in three volumes, which demonstrate his imamate and the vastness of his knowledge. Prior to him, the Imam did not have an independent school of thought (*madhhab*), until he tracked down the texts of Ahmad, documented them, and substantiated them with evidence after the year three hundred. May Allah Almighty have mercy upon him." End quote.
– He also stated (11/331) after mentioning those who narrated from Imam Ahmad, may Allah have mercy upon him: "Abu Bakr al-Khallal gathered the entirety of what these individuals possessed of the statements of Ahmad, his verdicts, and his words regarding *Al-'Ilal*, *Al-Rijal* (Biographies of Narrators), *Al-Sunnah*, and *Al-Furu'* (Branches of Jurisprudence), until he acquired an indescribably large amount of that. He traveled to various regions to attain it, writing from approximately one hundred individuals among the companions of the Imam. Then he wrote much of that from the companions of his companions, and some of it from a man, from another, from another, from Imam Ahmad. He then began arranging, refining, and categorizing it into chapters... And amidst that, he narrates from the high hadiths he possessed, from the peers of Ahmad among the companions of Ibn 'Uyaynah, Waki', and Baqiyyah, which testifies to his imamate and precedence. He authored the book *Al-Jami'* in over ten volumes, or more. He stated in the book *Akhlaq Ahmad bin Hanbal* (The Character of Ahmad bin Hanbal): 'I know of no one who was ever devoted to the rulings of Abu 'Abdullah as I have been devoted to them.' Likewise, Abu Bakr al-Marrudhi, may Allah have mercy upon him, used to say to me: 'No one has been devoted to the rulings of Abu 'Abdullah as you have been devoted to them, except for a man in Hamadan called Mutawwayh, whose name is Muhammad bin Abi 'Abdullah; he compiled seventy large sections (*ajza'*).'" End quote.
– Ibn Taymiyyah stated in *Majmu' al-Fatawa* (34/111): "Indeed, the speech of Ahmad is very vast and widespread, and rare is the one who precisely captures all of his texts in many of the issues, due to the abundance of his speech, its spread, and the large number of those who acquired knowledge from him. Abu Bakr al-Khallal toured the lands, compiling approximately forty volumes of his texts concerning matters of jurisprudence, yet many things evaded him that are not in his books. As for what he compiled of his texts regarding the fundamentals of religion (*Usul al-Din*), such as the book *Al-Sunnah*, it is approximately three volumes; and similarly the fundamentals of jurisprudence and hadith (*Usul al-Fiqh wa al-Hadith*); and similarly the book *Al-'Ilal*, which he compiled from [Ahmad's] speech concerning the hidden defects of hadiths... and from his speech regarding the actions of the heart, ethics, and etiquette; and from his speech regarding narrators and history. Thus, despite its abundance, he did not comprehensively encompass all that people transmitted from him." End quote.
