When bodies absorb heat, the temperature increases. How does it happen? Does it not transfer the heat to the colder surrounding due to the process of radiation?

Yes, any hot body continuously emits the heat to surroundings through radiation.

When the amount of heat that is absorbed by the body is more than heat radiated by the body to surroundings, the temperature of the body increases.

When heat that is absorbed by the body is less than heat radiated by the body to surroundings, the temperature of the body decreases.

When heat that is absorbed by the body is equal to heat radiated by the body to surroundings, the temperature of the body remains constant.
