My cousin left Islam and joined Hinduism, do I keep ties with her? If yes, how do I treat her?
Shaikh Adil As-Sayyed:
You need to try to talk to her and remove any doubts she might have. Do not give up, there were people who apostated after the death of the Prophet, peace be upon him, and when the Companions talked to them they repented and came back to Islam.
Then after you try your best, if she insists on disbelief and she lives by herself, independent from her parents, then you cut ties with her.
