من فارق عليا فارقني، ومن فارقني فارق الله.
Whoever parts from ‘Ali has parted from me. And whoever parts from me has parted from Allah.
This hadith is narrated from Ibn ‘Umar, Buraydah, Abu Dharr, and Abu Hurairah radiya Llahu ‘anhum.
Al Tabarani and others narrate —from Ahmed ibn Subayh al Asadi — Yahya ibn Ya’la narrated to us — from ‘Imran ibn ‘Ammar — from Abu Idris — Mujahid narrated to me — from Ibn ‘Umar radiya Llahu ‘anhuma: “Indeed, the Messenger of Allah salla Llahu ‘alayhi wa sallam said…”
This hadith is munkar (unacceptable).
Ibn Hajar says regarding Ahmed ibn Subayh al Asadi: “Abu al ‘Arab mentions him in his work Kitab al Du’afaʾ. It was transmitted from Abu al Tahir al Madini that he said, ‘He is from Kufah. He is worth nothing.’”
Yahya ibn Ya’la is (Yahya ibn Ya’la) al Aslami. He is da’if (weak).
Abu Idris could not be traced.
Al Tabarani narrates — Muhammad ibn ‘Abdul Rahman ibn Mansur al Harithi narrated to us — my father narrated to us — Hussain al Ashqar narrated to us — Zaid ibn Abi al Hassan narrated to us — Abu ‘Amir al Murri narrated to us — from Abu Ishaq — from Ibn Buraydah — from his father who said: “The Messenger of Allah dispatched ‘Ali as an amir (leader) over Yemen…’” He went on to mention a lengthy hadith in which Nabi salla Llahu ‘alayhi wa sallam mentioned a similar supporting statement (as the original hadith).
I do not know who Muhammad ibn ‘Abdul Rahman ibn Mansur al Harithi and his father are.
Al Hussain ibn al Hassan al Ashqar is da’if (weak). Some hadith critics accused him of lying.
I could not trace Zaid ibn Abi al Hassan and Abu ‘Amir al Murri.
Abu Ishaq is (Abu Ishaq) al Sabi’i. He is a mudallis (obfuscates when he narrates) and a mukhtalit (commits serious errors).
Al Haythami says: “Al Tabarani narrates this hadith. It contains a number of narrators in the chain of transmission that I do not know. The majority of hadith critics regarded Hussain al Ashqar as da’if (weak) and Ibn Hibban regarded him as a thiqah (reliable).”
Al Albani transmitted the hadith from al Haythami’s Majma’ al Zawaʾid and said: “It is da’if jiddan (extremely weak).”
Al Hakim and others narrate this version of the hadith with a chain of transmission that is da’if (weak).
The chain of transmission contains a narrator by the name of Muawiyah ibn Tha’labah. Abu al Jahhaf is the only person to narrate from him and Ibn Hibban is the only person to deem him a thiqah (reliable). Abu al Jahhaf’s name is Dawood ibn Abi ‘Awf. There is a difference of opinion regarding his status.
Al Hakim authenticated the hadith. Al Dhahabi disagreed and said the hadith is munkar (unacceptable).
Al Albani (also) regarded the hadith as munkar (unacceptable).
Al Dhahabi and Ibn Hajar write:
Al Azdi says that Razin al Kufi al A’ma is matruk (suspected of forgery) from Abu Hurairah. Habib ibn Abi Thabit narrates from him. Thereafter, al Azdi mentions the following long batil (false) hadith for him from Abu Hurairah that is marfu’ (attributed to the Prophet salla Llahu ‘alayhi wa sallam): ‘Whoever separates from me has separated from Allah. And whoever separates from ‘Ali has separated from me. And whoever places him in charge has placed me in charge…’
In short, the hadith is munkar (unacceptable). All of the different chains of transmission are wahiyah (feeble).
