Musannaf Ibn Abi Shaybah 16955 — Women of the People of the Book when

Urwah bin al-Zubayr reports that they said regarding a woman of the People of the Book: When she comes from the land of war, entering the land of the Arabs under a guarantee of safety (aman), then if she shows that she has settled down in the land of the Arabs, there is no harm in a Muslim marrying her; but if she does not show that except at the time of the marriage proposal, she is not to be married.
