I’m not sure but let me give u an example. What is purpose of Qura’n if u keep it covered in a beautiful designed reshmi cloth and never read/recite it. Keeping it covered will help u in this world or on the day of judgement or will increase ya knowledge? I think the answer is No.
So same if u wear taweez (written some Quranic ayat or words etc) sealed, will help you?
Yes! if u read, recite and remember it in ya mind it will surely help you in this world and on the day of judgement and i’m pretty sure u knw how.
