Machine translationRead the Arabic original
Question:
The questioner says: Is it permissible for the husbands of my sister's daughters that I uncover my face for them and greet them with my face uncovered, or is it not permissible?
Answer:
You are not a mahram to them. You are their maternal aunt, the maternal aunt of your sister's daughters. So the husbands... are not mahrams to you. Your sister's husband is not a mahram to you, and you are not a mahram to him. Rather, it is your mother's husband, your grandmother's husband, which is different from your daughter's husband, which is different. There is no harm. As for the sister's husband and the sister's daughter's husband, no, they are not mahrams.
