It is narrated from Sayyidah Razinah (may Allah be pleased with her) (the freed servant of the Messenger of Allah (peace and blessings be upon him)) that "the Messenger of Allah (peace and blessings be upon him) took Sayyidah Safiyyah (may Allah be pleased with her) as a war captive on the day of the conquest of Banu Qurayzah and Banu al-Nadir, and he (peace and blessings be upon him) was bringing her along as a captive. Then, when she saw the (Muslim) women, she called out: 'Ashhadu an la ilaha illallah, wa annaka Rasulullah' (I bear witness that there is no true god except Allah, and that you are indeed the Messenger of Allah). So the Messenger of Allah (peace and blessings be upon him) released her, while her arm was in his (peace and blessings be upon him) blessed hand; then he (peace and blessings be upon him) freed her, proposed marriage to her, married her and gave her a dowry (mahr)."
