Ibn Abi Umayr narrated from Ibrahim ibn Abd Al-Hamid who said: I asked Abu Abdullah عليه السلام about a Christian man who accepted Islam and then reverted to Christianity and died. Imam عليه السلام said: "His inheritance goes to his Christian children." I then asked about a Muslim who converted to Christianity and then died. Imam عليه السلام said: "His inheritance goes to his Muslim children."
