In the coming argument please remember that if either Pardew or Ben Arfa has said something that supports the hypothesis that Pardew has not mishandled Ben Arfa's return from injuries then it is to be taken as gospel.
However, if Ben Arfa has said something which does not support that hypothesis (like saying im 100% fit and subsequently not playing/starting. see:last season and this) then it is to be discounted immediately and ignored.
