Aishah narrated that: The Messenger of Allah said: "Whichever woman married without the permission of her Wali her marriage is invalid, her marriage is invalid, her marriage is invalid. If he entered into her, then the Mahr is for her in lieu of what he enjoyed from her private part. If they disagree, then the Sultan is the Wali for one who has no Wali".
This hadith teaches us that we should always seek permission before entering into any kind of marital relationship and that we should respect our guardians’ decisions when it comes to matters such as these. It also reminds us that even if something goes against Islamic law, justice must still prevail and all parties involved must receive what they are due according to Islamic teachings.
