My age is 22. My two elder sisters and brothers got married and also I have 3 younger sisters (all are matured). I want to ask about “purdah”. My question is “is purdah imported within family between us (brother-in-law-sister-in-law-sisters-me-mother-father)”.
بسم الله الرحمن الرحيم
(Fatwa: 872/556/L=1434)
In the question mentioned above, it is necessary for you and your sisters to observe purdah from non-mahram men. A non-mahram is one with whom nikah is not haram forever. Hence it shall be necessary for you to observe purdah from your bhabhi (sister in law) and your sisters should observe purdah from their bahnoi (brother in law).
Allah knows Best!
