How sound is the story of the conversion of Addas to Islam with the Prophet, may Allah bless him and grant him peace?

There is no authentic text indicating the conversion of Addas to Islam. His name is mentioned in books on the Companions (Sahabah), but the methodology of their compilers was to include everyone for whom a narration hinted at his companionship, without distinguishing the authentic from the weak among these narrations. The story of Addas has not been established with an authentic chain of transmission (isnad); rather, it is among the mursal narrations, meaning those with a disconnected chain. Furthermore, the reports that mention Addas after his meeting with the Prophet, peace and blessings be upon him, were exclusively narrated by Al-Waqidi, who is considered abandoned in narration. In conclusion: The story of Addas's conversion to Islam has not been reported with an authentic chain of transmission.
