Abu Bakr Muhammad ibn Rajāʾ (1) said, “I have never seen anyone like Ahmad ibn Ḥanbal, nor have I met anyone who has seen his equal.”

Abu Zurʿah al-Rāzī stated, “Among the living scholars whose hair is still black, I know no one more versed in jurisprudence than he.”

Al-Bayhaqī transmits from al-Ḥākim, from Yaḥyā ibn Muḥammad al-ʿAnbarī, who said: “Abu ʿAbd Allah al-Bushanjī recited to us, concerning Ahmad ibn Ḥanbal—may Allah have mercy on him—(2):

If you should ask who leads us—’tis Ibn Ḥanbal;
Upon his grasp the imams of humankind rely.
He followed the Prophet Muhammad once the ones
Who were the caliphs after him had passed away.
Step for step, like sandal-strap (3) to sandal-strap;
Whoever seeks a pattern finds his pattern there.

It is authentically reported that the Messenger of Allah ﷺ said:

“An ever-present group of my community will remain manifest upon the truth; those who forsake them or oppose them will not harm them until the command of Allah comes while they are still upon it.” (4)

ʿAbd Allah ibn al-Mubārak, Ahmad ibn Ḥanbal, and others said, “They are the people of hadith.”

Al-Bayhaqī also narrated—through Abu Saʿd al-Mālīnī (5), Ibn ʿAdī, Abu al-Qāsim al-Baghawī, Abu al-Rabīʿ al-Zuhranī, Ḥammād ibn Zayd, Baqiyyah ibn al-Walīd, Maʿān ibn Rifāʿah, and Ibrāhīm ibn ʿAbd al-Raḥmān al-ʿAdhrī—. Al-Baghawī added: “Ziād ibn Ayyūb told me; Mubashshir narrated to us, from Maʿān, from Ibrāhīm ibn ʿAbd al-Raḥmān al-ʿAdhrī, who said: The Messenger of Allah ﷺ declared:

“In every generation, the upright among them will carry this knowledge, repelling from it the distortions of the extremists, the fabrications of the false claimants, and the misinterpretations of the ignorant.” (6)
