What is the authenticity of the hadith: "Searing from the Fire will surely afflict people for sins they have committed," and is it an abridged version, requiring the mention of the full hadith, and what should be done towards those who spread it?

The aforementioned Hadith is authentic, narrated by Al-Bukhari from Anas, and it states: "Indeed, some people will be afflicted by scorches from the Fire due to sins they committed, as a punishment. Then Allah will admit them into Paradise by virtue of His mercy. They will be called Al-Jahannamiyyun (the Hell-dwellers)." The question's confinement to a part of the Hadith is an instance of fragmenting a Hadith, which Al-Bukhari permits if it does not corrupt the meaning. If the intention is to prove that some monotheists will enter Hell due to their sins, then this is correct. Otherwise, the original meaning of the Hadith is the exit of some people from the Fire by Allah's mercy, and this is not clear from the mentioned fragment.
