Umm Kulthum bint 'Uqba

At the Treaty of Hudaybiyyah, Umm Kulthum bint Uqba, daughter of Prophet's enemy Uqbah bin Abu Mu'ayt, sought asylum with the Muslims when she learned that a revelation (60:10) had said that women seeking the Prophet did not have to be returned to their families and men, unlike the custom for male escapees.
