What is the ruling on sitting with someone who does not pray or fast, denies and mocks the hijab and those who wear it, and mocks Sayyidah Aisha (may Allah be pleased with her), given that this person is a blood relative?

The actions mentioned, such as abandoning prayer, denying and mocking the hijab, and ridiculing the Mother of the Believers, Aisha, are considered acts of disbelief (kufr) and apostasy from Islam. The perpetrator of these actions must be advised. If they persist in them, they must be boycotted, shunned, and not greeted with 'peace' (salam), unless the purpose of sitting with them is to advise them or to warn others of their evil.
