The daughter of my paternal uncle's son married my maternal uncle and I married his daughter, then he divorced his wife and I too divorced his daughter. I want to marry the daughter of my paternal uncle's son.
Is it permissible for me to marry her?
It is permissible for you to marry the daughter of your paternal uncle's son. Her being previously married to your maternal uncle does not make her unlawful for you to marry. Likewise, your marriage to your maternal uncle's daughter does not prohibit you from marrying the daughter of your paternal uncle's son. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
