Please what is the authenticity of the hadith below
Salam, Bro try not to go off-topic, whenever you wish to ask something open a new thread with a clear descriptive title in the correct section.
As for that Hadith, I saw it narrated by al-Hakim, al-Nasa'i and al-Tabarani with the same chain:
عَمْرُو بْنِ حَمَّادِ بْنِ طَلْحَةَ الْقَنَّادُ، ثنا أَسْبَاطُ بْنُ نَصْرٍ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ عَلِيًّا رَضِيَ اللَّهُ عَنْهُ، كَانَ يَقُولُ
... -> `Amro al-Qannad -> Asbat bin Nasr -> Simak bin Harb -> `Ikrimah Mawla ibn `Abbas -> `Abdullah ibn `Abbas
1- `Amro ibn Talhah is called a Rafidi apparently for his hatred of `Uthman, though he is truthful and it is disliked to take `Ali's virtues from his likes for obvious reasons.
2- Asbat al-Koufi is honest but makes a lot of mistakes and has narrated unsupported reports from Simak.
3- Simak bin Harb is honest with bad memory, he got confused at the end of his days and his narrations from `Ikrimah are shaky.
4-`Ikrimah the servant of ibn `Abbas whom the Rafidah accuse of being an evil Nasibi liar. Obviously they'll disregard it if he's narrating `Ali's virtue. He is trustworthy and very reliable when it comes to Ibn `Abbas's narrations.
Ruling: Weak Hadith.
Although there is no issue in accepting it out of lenience since it's a report in virtues and the text is not problematic.
`Ali says at the end of the report:
ﻭﺍﻟﻠﻪ ﺇﻧﻲ ﻷﺧﻮﻩ ﻭﻭﻟﻴﻪ ﻭﺍﺑﻦﻋﻤﻪ ﻭﻭﺍﺭﺛﻪ ﻓﻤﻦ ﺃﺣﻖ ﺑﻪ ﻣﻨﻲ
[By Allah, I am his brother, his beloved friend, his cousin and his inheritor so who has more right to him than me?]
I don't see an issue.
