Is it necessary to distance oneself from the Qubaysiyat due to some innovations they have, such as celebrating the Prophet's birthday, the "Nariya" prayer, and extinguishing lights when mentioning God, and not because of their extremism regarding righteous people or their blind obedience, as is rumored?

One must honor their mother and keep her company with kindness due to her great right, and maintain ties of kinship such as maternal uncles and aunts, and not sever them. If an innovation (bid'ah) appears from a relative, one must avoid their falsehood and denounce it, while continuing to maintain ties with them kindly, unless boycotting becomes a necessary means to deter them from innovations and reprehensible acts.
