Authenticity of a Hadith regarding the Prophet SAW & Ali RA being in a state of janaba in the mosque

>Narrated by Abu Sa’id (ra) from the Prophet (Peace be upon him) who said to Ali (ra): O Ali, it is not allowed for anyone to be in state of seminal impurity in this mosque, “**except for me and you**” [Sunan Tirimdhi, Volume No. 1, Page No. 535 where Imam Tirimdhi declared it “Hassan”] According to [this](https://www.dar-alifta.org/Foreign/ViewFatwa.aspx?ID=10509) , there are ahadith which state that those in a state seminal impurity, not just the Prophet SAW or Ali RA, are allowed to be in mosques. Is this particular hadith truly authentic?
