Dear Student ,
When a body lies on a rough and inclined plane and does not move then the frictional force will be greater then the limiting frictional force will act on the upward direction and the resultant of component of forces acting on the body in the both horizontal and vertical direction in that inclined plane will be zero .
Hope it helps .
