Is my marriage to a woman with whom I had anal intercourse before marriage, knowing that she had previously engaged in this act and repented, considered a lawful marriage?

Anal intercourse is forbidden and a grave sin, and it necessitates a prescribed punishment (hadd). However, repentance erases what came before it. If a woman marries after her repentance, the marriage is valid, and her previous engagement in the forbidden act does not affect it. The wife erred by disclosing this, because it is obligatory for one who has fallen into disobedience to conceal their own sin. Therefore, it is necessary to conceal it, remain steadfast in repentance, maintain righteousness, and cooperate in obedience to Allah.
