Is it permissible to seek healing by mentioning the beautiful names of Allah, meaning to mention a specific name for each illness, believing that this name cures that illness?

Allah has commanded us to invoke Him by all His Most Beautiful Names. It is best to choose the name appropriate for the need, such as "O Forgiving, O Merciful" for forgiveness. Allah's Names have varying degrees of excellence, and the Greatest Name of Allah has been mentioned in the Hadith. The excellence of some names over others does not imply any deficiency in those less excellent; rather, all of them are perfect. There is no validity to the belief that each name has special properties or secrets, or that each name has a spiritual servant, or that it cures a specific illness; this is a statement made without knowledge.
