Befriending Ahmadiyyah's and maintaining family ties with people involved in sin
Q: I have two questions:
1. How to deal with people called Ahmadiyah? A girl was apparently wearing a hijab like Muslim women do and I grew friendly with her but now I came to know she is Ahmadiyah and not Muslim. What should I do?
2. How to deal with relatives who are involved in *gunnah e kabeera* or greatest sins. They also perform black magic and admit it. Is the prohibition of not cutting off with relatives still there for us? When these people also harm my family and try to create obstacles for every important thing.
