If a man accepts another religion after he has been a Muslim. How does it affect his life and his marriage?
A person who becomes an apostate, i.e., rejects Islam after having been a Muslim, severs all his ties with his Muslim family. His wife is immediately separated from him (if she is a Muslim) and they are no longer married. She is free to marry someone else after making sure she is not pregnant by observing a waiting period. One the other hand, a Muslim woman cannot be married to a non-Muslim, no matter what religion he follows. When her husband becomes a non-Muslim, that condition takes precedence over the marriage contract and cancels it altogether.
