AL-MUMTAHINAH الممتحنة
Lit. “She who is tried.” The title of the LXth Surah of the Qur’an, from the expression in the 10th verse: “O believers I when believing women come over to you as refugees, then make trial of them.”
Al-Baizawi says: “When such women sought an asylum at al-Madinah, Muhammad obliged them to swear that they were prompted only by a desire of embracing Islam, and that hatred of their husbands, or love of some Muslim, had not any influence on their conduct.”
