Using a stove in hotels that do not permit the usage of appliances in hotel rooms

Q: It is a general rule in most present day hotels that visitors booked in are not allowed to use a stove or any such appliance in the bag which may be a cause of a fire. Despite the above condition, a person still uses the appliance without it being detected by the hotel, will this be incorrect and be regarded as khiyaanat (deception)?

Backbiting

Q: If someone is mentioning something bad about a person who he knows but is unknown to me, is it backbiting? Will we both be sinful?​
