It comes from angular momentum. Angular momentum is a conserved quantity of physics. That means that the sum of angular momentum of the universe is constant, even though some parts of the universe may transfer angular momentum to other parts.
We do not know the total amount of angular momentum of the universe, but from observations we know that it is not uniformly distributed. This explains why celestial objects rotate.
If the total amount of angular momentum of the universe would be zero it would be theoretically possible that rotation could cease in the future. However, nobody knows the ultimate fate of the universe, so this is purely speculative.
