Assalaam Alaikum Wa RahmatULLAHI Wa Barakatuhu.
Q:Are the paternal and maternal uncles of the husband including fathers (as in father of the father in law or father of the mother in law) of the in-laws mahram to the bride?
Wa Alaikum Assalaam,
الجواب و بالله التوفيق
The paternal and maternal uncles of your husband are not Mahram to you (as the wife). Your husbands’ father and grandfather are mahram to you.
The father of your Mother in law (i.e. your husbands’ grandfather from his mother’s side) is a Mahram to you.
And Allah Knows Best.
