Q: Parents responsibility if a daugheter has married a non muslim. Will Allah Ta’ala’s punishment be on the parents and family?
A: They should repent. Perhaps on account of them not giving their child the right deeni guidance the child has unfortunately involved herself in haraam. Make du`aa for her and beg Allah Ta`ala’s forgiveness, and very gently and lovingly bring her back.
And Allah Ta’ala (الله تعالى) knows best.
