Is it permissible for a girl to remove her hijab in front of her mother's or father's maternal uncle or paternal uncle?

The mother's maternal uncle (khal al-um) and paternal uncle (ammuha) are considered mahram (definition) to a girl, and she is permitted to uncover in front of them. This is because Allah Almighty mentions paternal aunts (ammatukum) and maternal aunts (khalatukum) in the verse of prohibited relations in Surat An-Nisa: "Prohibited to you are your mothers, your daughters, your sisters, your paternal aunts, and your maternal aunts." This includes the paternal aunt of the mother and father, and the maternal aunt of the mother and father, which indicates that each of them is mahram to the girl.
