May Allah cure him and restore his health back again! You must continue to make ruqya on him as this is the only solution. You should also ask Allah in prostration while praying to cure him.

I would like to ask you for a favour. My brother was inflicted with magic over 12 years ago. We have done ruqia on him many times, but doesn’t get healed. Sometimes he gets little bit better, but now he doesn’t allow anyone to read on him (ruqia) I would like to ask you to ask Allah to show me way out of this, as you are more pious than i am, maybe Allah will answer your dua
