“Abu ’Abd Allah (a.s.), has said, ‘If a woman becomes Muslim and she is married in a way that is an un-Islamic way, they must be separated.’ I then asked him (the Imam) about the case of a man who migrates and leaves his wife among the pagans, then she joins him; if he can keep her with the first marriage or that her safety is cut off. He (the Imam) said, ‘He can keep her; she is his wife.’”
