Dear Mifti Saheb. As-salamualaikum. Are the following people mahram or ghayr mahram : 1) Mother’s sister or father’s sister. 2) Step mother’s sister and step father’s sister. For females, step mother’s brother or step father’s brother. 3) Step mother’s brother’s wife ( step maternal uncles? wife). 4) Sister’s mother in law.
Mother’s or father’s sisters are Mahrams and all relations of your
step-mother or step-father are Ghayr Mahrams. Sister’s mother-in-law is
Ghayr Mahram. (Aalamgiri)
and Allah Ta’ala Knows Best
