The 28-year-old arrived at the Kingfield Stadium from Dagenham & Redbridge on a initial one-month deal in February.
However, having impressed during his five outings for the Cards, he will now remain a part of Garry Hill's squad for their six remaining fixtures.
Woking have lost just one match in which Saah has featured.
