What is the ruling on the oath "Divorce upon me, I do not know them" for a person who saw his wife's name on his device along with the names of two girls whom he does not know?

If a person swears an oath of divorce that he does not know two individuals, and then it becomes clear to him that he does know them, and the oath was based on his assumption that he did not know them, then the divorce does not take effect. It is obligatory to be cautious about swearing oaths of divorce and to avoid acquaintances and conversations between young men and young women through social media.
