What is the ruling of Islamic law regarding the marriage of a girl whose marriage contract was solemnized with a committed man, but she became alienated from him after falling in love with another young man, and she still wishes to marry the other young man, despite her father's refusal of this marriage?

First: The necessity of avoiding relationships between genders due to the temptations they entail. Second: Do not blame yourselves for what happened to your sister, for you did not fall short in raising her, and her parents agreed to her leaving the co-educational school, and she married a righteous man.

Third: It is not permissible to force a girl to marry someone she dislikes, and a father is not considered to be preventing his daughter from marrying if he prevents her marriage to someone whose religion and character are not satisfactory.

Fourth: Advice for dealing with the situation: 1. Do not mention what happened to any relatives or strangers. 2. Do not disown your sister; rather, support her and try to persuade her to return to righteousness, reminding her of the impermissibility of what she did and its negative consequences for her and the family. 3. If she insists on marrying the young man, marry her to him on the condition that his religion and character are sound. This is better than the continuation of a forbidden relationship and the evils that result from it, while delaying consummation after the marriage contract until matters become clear to her. 4. "Nothing like marriage has been seen for two who love each other," so marriage is the solution for the relationship, for it brings stability and love, and elevates one from sin.
