Is a person's questioning the authenticity of the narration that Prophet Muhammad was the most afflicted of the prophets considered a refutation of the Companion and a denial of the Hadith?

Intrusive thoughts (hadith al-nafs) are not held accountable in Islamic law, nor is a firm belief contrary to a sound hadith due to ignorance of its authenticity or meaning. As for the hadith of Al-Miqdad ibn Al-Aswad with the wording mentioned, we have not found it. However, a hadith was narrated from him in which he blames those who wish to see the Prophet, peace be upon him, explaining that many saw him and Allah cast them into Hell, and reminding of Allah's favor upon those whom He brought forth knowing no one but their Lord. Regarding our Prophet being the most afflicted of prophets, he, peace be upon him, said: "No one has been harmed as much as I have been harmed in the way of Allah," and it was narrated that he said to 'Aisha: "O 'Aisha; I am the most afflicted of people."
