This is true, she is not required to do any household chores for them, she is not their slave or servant.
Is my mom wrong if she expects her daughter in law to help her in every household chores..I heard from a speaker that,in Islam daughter in laws should be respectful and courteous towards their in laws..she will not be held responsible if she is not obedient towards them..is this correct? And Can u please shed some light on responsibility of daughter in laws towards her in laws
