I am a Muslim who has family members which are not practicing Islam. They have witnessed clear signs of Allah like someone being possessed with Jinn and reacting to the recitation of the Qur'an but they turned away and did not change their ways. They still persist in sin and transgression in forms like: Not praying (some not praying at all while others pray irregularly), drinking alcohol, not covering themselves, going to the magicians and asking them, spraying water of magicians in their homes, celebrating the festivals of the disbelievers, making friends with them, not attending Jumah, completely shaving the beards.
They claim to be Muslims and they saw clear signs of Allah that they need to return but still refuse. I fear for myself because they are involved in going to the magicians and I fear that they may harm me because of their superstitious lifestyle. They accused me of being the cause of their problems although I am a practicing Muslims who does not visit magicians and causes harm to the people. Alhamdulillah.
They accused me and my mother in the past of horrible things and we are not sure if it is safe to go to them because of them being involved in going to magicians. They started to sever ties by not helping us in times of hardship and ignoring our problems and not visiting us during these times. It is almost 4,5 years that these people persist in sin and transgression and severing ties. They are today basically known for their evil and this is why we avoid them. My and mother have developed a deep hatred for the sake of Allah because these people commit sins openly during the day and they don't care.
Is it permissible for me to avoid them as long as they don't repent to Allah and mend their ways? Or am I sinful? These people know about prayer, fasting and so on but they refuse to practice Islam correctly out of their own choice not because of ignorance.
