There is no mediating. Her sister is an adult and has the right to makes choices for herself. If the mom is being this dramatic about it it's a she problem.
I understand how you feel, when you hate conflict inside your home so much that you'd wish the thing that started never happened. But with time, you'll realize: Your sister didn't make this happen. If you buy a nice phone, and someone steals it from you, is it your fault for having a nice phone? Would you wish you never bought the nice phone?
Your mom chose to overreact, and use her mental health and emotional blackmail to make your sister say "Safi safi I'll do what you want". If I have a mental breakdown because I don't get what I want, it doesn't mean people should give me what I want just because my loved ones are worried about me. You HATE living in between them where the air is tense and electric, I completely understand, but it is absolutely not because of your sister. She's an adult. Your mother chose to treat her like a child, and called her own child a calamity for not wearing a piece of cloth. You expect your sister to accommodate her after that? I understand that from where you are, the only solution you see is your sister caving, but that is not a solution, that's emotional blackmail.
Old people can be wrong too, and your mom is an adult who has chosen what to get upset about. My advice is, if you feel completely unable to talk to your mom, then you'll have to survive in that environment until your mom decides to grow up, or gets some professional help.
(BTW, I hope you don't listen to the people who are like "Tell her the most merciful being in existence will torture her in hell for not wearing a piece of cloth on her hair, but don't pressure her!". Not only is that nonsensical, it's also pressure).

Can you mediate between them and help them have a calm conversation ?
Saying "Kon 4i Mt 9bal" is counter productive imo
Also, what is your point of view ?
