Is it permissible for my aunt’s daughter to uncover her face, given that she was breastfed by my uncle?

Question:
In his second question, he asks: Is it permissible for my aunt’s daughter to uncover her face in front of me, given that she was breastfed five times by my uncle?

Answer:
If she was breastfed five times by your mother, then she is a mahram (a relative one may not marry) to you. However, if your aunt’s daughter was not breastfed five times, or was not breastfed at all, then she is a stranger to you. It is not permissible for you to be alone with her, and it is not permissible for her to uncover for you what is required to be covered.
