Simak bin Harb narrates: A man came to Sayyiduna Ali (may Allah be pleased with him) and said: "There is a girl, I am her guardian, and she has married without my permission." So Sayyiduna Ali (may Allah be pleased with him) said: "Regarding what this girl has done, our opinion is that if she has married someone of equal status (kufu’), then we will let it stand; but if she has married someone who is not her equal, then we will give you (the guardian) the choice (to let it stand or annul it)."
