I just correct your words that word "Muslim" isn't flame.
You should /p on the time when he flamed you. Now it's late.
/p commands stands for checking namespoofers ingame, also /time command is needed.
Oh, one more thing, on your case /p isn't needed cause those words are whispered to you. Clearly, not namespoof. /time command would resolve the matter and mods will see on screenshoot what realm it is.
