and also who do we know is a wali of Allah (Swt) like the famous wali of Allah (swt) are his Prophets (saw) and even Ibraheem (as) was named as khalil Allah (swt), because they are the real deals

so we dont know who is a real awliyah or who isnt, nowadays just because someone has a beard, and is claimin he knows "stuff" to cure people, people think he is a awliyah! so Allah hu alim, the Quraan and Sunnah, has all the cures, we dont need permission from anyone to read them, we can read them whenever we wanttt
