Dealing with relatives who do not disavow the Ismailis

Question:
The questioner says: My relatives who do not disavow the Ismailis, honor them, visit them in their homes, and share in their joys and sorrows with them, despite the fact that I advise them frequently and have explained things to them, but to no avail. He asks: Is it permissible to boycott them, and what should I do with them? I ask for your advice and guidance, and I ask that you advise them.

Answer:
This is a matter in which some Muslims in their lands have been tested, having among them people of other religions, sects, and misguided groups. However, these people deal with them in worldly matters, the permissible ones, and deal with them in those. As for matters of religion, we disavow them to Allah and do not participate in their religious works or their religious customs that display their religion and their misguidance. We do not participate in this, nor do we encourage it; rather, we distance ourselves from them. As for worldly matters...
...buying and selling, and exchanging visits, without compromising religion and without affection in the hearts, but only for the sake of worldly interests, then there is nothing wrong with that, considering that they have been tested with them and they are in their lands, so they deal with them in worldly matters. As for matters of religion, they disavow them and do not participate in their misguided customs and traditions or their false sects. Yes.
