Thabit bin Wadee’a Al-Ansari:
There is only one report in which Thabit bin Wadee’a is mentioned. In the report, he is among those that Ali asks if they have heard the hadith of Ghadir. Thabit is one of those that affirms that he did.
However, the chain includes mostly anonymous narrators. Also, it include Al-Asbagh bin Nubata who was weakened by many hadith scholars. Abu Bakr bin Ayyash called him a liar as well. See his biography in Mizan Al-I’itidal.
