In a small bowl, combine the figs, marmalade, mustard and brown sugar. Separate crescent dough into four rectangles; seal perforations. Top each with ham and spread 1/4 cup filling to within 1/4 in. of edges. Roll up each jelly-roll style, starting with a short side; pinch seams to seal. Cut each into six slices.
Place the slices cut side down on greased baking sheets. Bake at 375° for 12-14 minutes or until golden brown. Serve warm.
