Is it permissible to abandon one's parents who practice sorcery and harm their young daughter, and what should be done regarding them?

It is impermissible to accuse anyone, especially one's parents, of sorcery without clear evidence. One must honor them and accompany them with kindness, even if they are polytheists, for Allah the Almighty says: "And if they should strive to make you associate with Me that of which you have no knowledge, then do not obey them, but accompany them in [this] world with kindness." Part of honoring them is to forbid them from sorcery and explain its danger. If harm is feared from visiting them, harm can be avoided by other means. Otherwise, it is sufficient to contact them or visit them without bringing along anyone for whom harm is feared, for obeying them is obligatory in matters that benefit them and do not harm the child.
