Is it permissible for me to marry my maternal aunt's daughter after marrying another woman, in order to sever a forbidden relationship and mend broken ties?

The questioner is not at fault for marrying a second wife if he is able to fulfill the material and moral rights of his wives. Marrying another woman is permissible for whoever has the ability to be just, as the Prophet, peace and blessings be upon him, said: “If a man has two wives and does not treat them justly, he will come on the Day of Resurrection with one side of his body drooping.”
