No transfer of heat is possible.

Conduction is the development of warmth through a substance by the movements of atoms. As the temperature of iron ball as well as the mug containing water is same, no heat transfer occurs.

Conduction or heat transfer happens only when two article at various temperatures are in contact with one another. Heat transfers from the hotter to the cooler article until they are both at a similar temperature.
