I have non-Muslim relatives.

Answer

Allah Ta'ala says in the Qur'aan Majeed: "These are the limits of Allah. Whoever transgresses the limits, verily he has oppressed himself."

The prescribed limits constitute the Shariah. Maintenance of family ties is valid, permissible and necessary only within the confines of the Shariah. If the lifestyle of the family members is in conflict with the Shariah, then it is necessary to avoid them even if they are Muslims, without showing hostility. Do not socialize much with them. If they are in need, assist them, but do not participate in their merrymaking and un-Islamic functions and haraam ways of life.

Breaking family ties for the Sake of Allah Ta'ala is an act of Ibaadat and necessary. It is called Bugdh fillaah - anger for Allah's Sake. The Ambiya (Alayhimus salaam) severed their family ties for the Sake of Allah Ta'ala. It is not permissible to fraternize and socialize with the family members even if they are Muslims when they are openly in conflict with the Shariah. The Mu'min's first allegiance is to Allah Ta'ala, not to the family.
