It's not as simple as that. The FSA is part of a coalition that includes islamists and which fights Assad, but it does not include ISIS. From what I know ISIS has done very little combat with Assad's forces and is hostile to other islamist groups. In fact, ISIS is hostile to everybody, and most of its combat in Syria has been about conquering land from other rebel groups.
