Musannaf Ibn Abi Shaybah

Hazrat Urwah bin Zubair states that the predecessors have said regarding the women of the People of the Book that if she leaves the land of war, she will enter the land of Arabia with security. If she openly settles in the land of Arabia, then there is no harm for a Muslim to marry her. If she only expresses settlement in the form of a marriage proposal, then marriage should not be contracted with her.
