Is marriage over the phone valid? And should the questioner continue his relationship with a girl he met over the phone and whom he is asking to marry after she has started memorizing the Quran, knowing that the girl’s mother divorced her husband before his death, then married customarily, then separated, and then married her first husband’s friend? What is the girl’s sin in her mother’s actions, and is it possible that she could become like her? What should the questioner do about this situation?

You should have asked about the religious ruling before committing the error. Therefore, fear Allah concerning yourselves, your hearts, and the hearts of Muslim girls. Do not follow the footsteps of Satan, who enjoins immorality and evil. The conditions for a religiously valid marriage are well-known: the girl's guardian (her eldest brother or paternal uncle, not her stepfather), witnesses, the dowry, and public declaration. What you did, a telephone marriage, is trifling with Allah's verses and transgressing His limits. The correct way to seek a girl's hand is to ask for her from her guardian and to perform the religiously sanctioned viewing of her. Cut off communication with her until the offer and acceptance take place between you and her guardian, in the presence of witnesses, and the contract is concluded. Before that, you must repent sincerely. If you see signs of goodness and righteousness in her, then strive to marry her and do not turn away from her because of her mother's sin.
