Does mocking the Dajjal or Satan, such as saying: "The Dajjal will ring your intercom to get to you," or fictional stories like: "A person eats hot food and deliberately does not say 'Bismillah,' then drinks water and says 'Bismillah' so that Satan eats the hot food and cannot drink water afterwards," count as mocking the verses of Allah the Almighty?

There is no evidence prohibiting mockery of Satan or the Dajjal for their own sake. Indeed, belittling Satan and angering him is religiously مطلوب (desirable), as in the saying "I seek refuge in Allah from Satan, the accursed," and Satan's weeping when the son of Adam prostrates, and his fleeing upon hearing the Adhan (definition).

However, if the intent of the mockery is to ridicule what has been authentically reported about them in sound hadiths, then this falls under mocking the verses of Allah.
