How authentic is the supplication surrounded by strange names such as: (Yamliha, Makthalina, Dafandoush), which is called "the supplication of sustenance or blessing"?

We have no knowledge of the sticker mentioned. As for the strange names mentioned, it is claimed that they are the names of the People of the Cave, and it is alleged that they possess properties not established by Islamic law. Supplicating through them in prayer, hoping for those properties, has no basis in Islamic law and is a blameworthy innovation.
