What should I do about my daughter whom I forced to get engaged to someone I now do not accept, and she insists on completing the engagement, while I feel guilty towards her and towards her former lover?

Parents must prevent their daughter from communicating with a foreign young man, and verify the suitor's religiosity and character. If he is not satisfactory in terms of religion and character, it is obligatory to remind the girl of the Prophet's instruction to choose a righteous husband. In this case, breaking off the engagement is permissible to avert harm from her.
