But thankfully, they were all mere rumours as the actor is still alive, a source close to the Khan family has said.
"I would request all to stop these rumours," she added.
Khan, 78, who has regaled the audience with his comic side in films like 'Himmatwala', 'Aankhen' and 'Coolie No.1' among several other entertainers, has been a victim of death rumours in the past as well.
Khan, due to old age problems, finds it difficult to walk and speak, and is under constant medical care at his Mumbai residence.
