Ahsanallahu ilaykum Supposing a woman has no wali at all and a random righteous man is appointed to be her wali. Can this wali see her without hijab? I don’t think so cause it’s still non mahram but I wanted confirmation from you

Ustadh AbdulAziz al-Haqqan

Go to the nearest official Islamic center for further assistance and don't just pick a random Muslim to be a wali.
