Grading: (2) This chain is very weak (da'if jiddan).
Technical note / Defect ('illah): About Ali bin Muhammad al-Hammadi (who is Ali bin Muhammad bin Abd Allah bin Muhammad bin Habib, Abu Ahmad al-Habibi), al-Daraqutni said: "He narrates manuscripts (nusakh) and munkar hadiths." Al-Hakim himself once described him with "lying" (kadhib), and once said: "He is too well known for weakness (lin) to be asked about." (See Tarikh al-Islam 7/909 and 8/35.)

Grading: This narration is also narrated through two other routes, but neither of them is of any worth at all (la yufrahu bihima: i.e. they carry no weight).
Technical note: Abu al-Bakhtari (in the chain) is "Sa'id bin Fayruz".

Reference / Source: Ibn Adi narrated it in "al-Kamil" (6/289) and Ibn Asakir in "Tarikh Dimashq" (30/73) through the route of Muhammad bin Abd al-Aziz bin Habib al-Dinawari, from Mu'adh bin Asad, from Ibn al-Mubarak, with this same chain.

Grading: Muhammad bin Abd al-Aziz al-Dinawari is "munkar al-hadith" and "extremely weak" (da'if bi-marrah).
Technical note / Defect ('illah): He narrated this very report on another occasion and gave it with an entirely different chain: there he narrated it "from Ali bin Ibrahim al-Marwazi, from Ibn al-Mubarak, from Mis'ar and Shu'bah, from Qatadah, from Anas". Ibn Asakir narrated it in "Tarikh Dimashq" (30/73). This is evidence that he did not retain the narration accurately (lack of dabt) and was inconsistent (idtirab) in it.

Reference / Source: Ibn Asakir (38/168) narrated it through the route of Ubayd bin Ahmad al-Himsi, from Sulayman bin Abd al-Hamid al-Bahrani, from Muhammad bin Abd Allah, from al-Muqri, from Mis'ar (alone), from Amr bin Murrah, from Abu al-Bakhtari al-Ta'i, who said: "I heard Ali", and then he mentioned the hadith.
Grading: Ibn Asakir said: "It is very gharib; I have only written it through this route."
Technical note / Defect ('illah): We say: Ubayd bin Ahmad is "majhul al-hal", and his shaykh Sulayman was accused of "nasb" (hostility to the Prophet's household) and is disputed; al-Nasa'i spoke very harshly about him and attributed lying to him, so he is the culprit behind it. In this narration it is stated explicitly that Abu al-Bakhtari heard from Ali (may Allah be pleased with him), whereas a number of scholars have denied that he even lived in Ali's time, let alone heard from him.
