May Allah swt bless the Holy Nabi saws, his family and ummah. May the saints’ stations be raised.
Will a taweez lose it’s power or effectiveness if it gets wet by accident inside where the paper is? Will the taweez become powerless if it is merely opened up even if it doesn’t get wet?
No, but restore the integrity of the taweez or get a new one. Amin to your du`a and may Allah bless you.
