It was narrated by Aḥmad (1/94) with an authentic chain of transmission.

The fifth is from ʿAbd al-Muṭṭalib ibn Rabīʿah ibn al-Ḥārith, attributed to the Prophet, with the wording: “O people! Whoever harms al-ʿAbbās has harmed me. A man’s paternal uncle is like his father.” Aḥmad (4/165) narrated it through Yazīd ibn ʿAṭāʾ, from Yazīd ibn Abī Ziyād, from ʿAbd Allāh ibn al-Ḥārith ibn Nawfal, who said: ʿAbd al-Muṭṭalib ibn Rabīʿah related to me …

I say: This chain of transmission is weak because of Yazīd ibn Abī Ziyād, a client of the Hāshim clan, who had poor retention. Yazīd ibn ʿAṭāʾ is similarly weak. However, I cited a corroborating report for it in al-Mishkāh (3156), by which it is strengthened.

The anonymity of a Companion does not detract from it, especially since Muḥammad ibn Abī Yaʿqūb identified him. ʿAbd al-Raḥmān ibn Mahdī narrated it to us and said: “ʿAbd Allāh”—meaning Ibn Masʿūd. Al-Ḥākim narrated it and said: “Authentic according to the conditions of the two Shaykhs, if Muḥammad ibn Abī Yaʿqūb retained it from ʿAbd al-Raḥmān ibn Mahdī.” Al-Dhahabī agreed with him.

I say: This Ibn Abī Yaʿqūb was trustworthy and one of al-Bukhārī’s teachers. His father’s name was Isḥāq. Thus, if
