There is a woman who took sahada 15 years ago.She doesn't pray ,fast,never give zakat and some times goes back to churches.She also goes to public pools with Swiming costumes,smokes ,wear shorts and says how much she misses eating pork. She celebrates christmas/Thanksgiving etc. Is she a muslim? Some says she could be a spy, then is it Islamic to stay away from this person for good? Is it better Islamically to avoid associating with such people for the Akhirah?
