What is the ruling on continuing an engagement to a girl whose appearance the suitor is not convinced by, despite her righteousness and religiosity, and is it permissible to break off an engagement due to not being convinced by her appearance, especially when fearing injustice, and particularly after repeated Istikhara prayers and an inability to settle on a decision?

If the girl is religious, of good character, and acceptably beautiful, then religiosity is the most important criterion in marriage and takes precedence over other qualities. It is recommended to repeat the Istikhara (prayer for guidance) and proceed with the marriage if her beauty is acceptable, for if there is good in it, Allah will facilitate it. However, if there is a fear that the marriage will fail, then it is preferable to break off the engagement, which is permissible out of need and disliked when there is no need.
