Deception

If a person has a disability but on the form he fills out to claim benefits he makes up some stuff about the help he needs for example he says he needs help eating and cutting up food when he doesn't and he needs help getting to the masjid but he can go on his own does the money he receives become haram as the amount of money he would get depends on the help he needs. So the person has got the actual illness (he hasn't lied about that) but just about the help he needs.
