Why do you need rotation?

It is necessary for a planet to rotate around a sun, or other large mass, because it is what allows the planet to stay at a fairly consistent distance away from the larger mass. If there was no rotation, the planet would go hurtling toward the mass. The rotation adds an outward acceleration to counteract the force of gravity from the larger mass.
