Musannaf Ibn Abi Shaybah 16953 — Women of the People of the Book when

Ubaydullah bin Abdullah bin Utbah, Sa'id bin al-Musayyib and Urwah bin al-Zubayr said regarding a woman of the People of the Book: If she comes out of the land of war, she enters the land of the Arabs under a guarantee of safety (aman). If she shows that she has settled down in the land of the Arabs, there is no harm in a Muslim marrying her. If she shows this settledness only at the time of the marriage proposal, she is not to be married.
