Asalaams… My family as a whole have a question: my sister some 7 years ago married a Christian… during that time we were not very religious… but now we realize that she cannot marry a non-Muslim… my sister still does not practice her ilam in her life… they now have 2 kids and the third on te way… what in our duty now towards her… should we inform her that she must divorce him? Should we not tell her nothing as it is not our duty? Should we just continue life as normal as nothing in wrong? What should we do? Please do shed some light in this matter… wasalaams.
