Nail Polish, Rings, Bracelets & Henna/Mendhi Patterns
These types of beautification is permissible in front of the Mahaarim ONLY, however it is impermissible for a woman to leave {the house} making this beautification apparent in front of Non-Mahaarim.
Allah says, “Do Not Expose/Make Apparent Your Beautification/Adornment”
Making apparent your beautification from ornaments in your hands or necklaces or earrings, all of that is from the prohibitions. It is not permissible for the woman to make apparent her beauty rather it is obligatory upon her to cover it {infront of Non-Mahaarim}
