Is Friction the Reason Spinning Tops Eventually Stop Rotating?

[avito009]

As per Newton an object that is rotating at constant angular velocity will remain rotating unless it is acted upon by an external torque.

But we know that a top will stop rotating after some time. So does that mean that the external torque is the friction of the floor on which the top rotates?

Yes, Because the point of contact between the spinning top and the surface is not an infinitesimal point.
