Taarabt has been consistently linked with a move away from Loftus Road for the past two years, with rumours of interest from Arsenal and Paris Saint-Germain.
Faurlin has admitted that losing Taarabt in January would be a hammer blow to the Hoops' hopes of surviving in the Premier League.
He told the Fulham Chronicle: "Adel is a very important player for us.
"It would be a huge blow for us if he leaves, but I don't think he will."
Mark Hughes's side continue to search for their first win of the season this weekend in a clash with relegation rivals Southampton.
