A paternal half-brother marrying a maternal cousin
Q: I have two brothers. My maternal aunt is called `Aishah who has two daughters; one of them is called Nurah who has also got daughters. My mother once told me that we are related to the daughters of her sister, `Aishah, through breastfeeding. My father `Umar Al-`Itawy married a second wife called Hissah who bore him sons and daughters. Then he married a third wife called Hasna' who bore him a son called `Abdul `Aziz who wants to marry the daughter of our maternal cousin Nurah.The question is:
Is it permissible
for our step-brother, `Abdul `Aziz, to marry the daughter of our maternal cousin Nurah?May Allah protect and guide you. May Allah's Peace, Blessings and Mercy be upon you.
It is permissible for your brother, `Abdul `Aziz, to marry the daughter of your maternal cousin provided that neither the daughter nor her mother is known to have been breastfed by any of the wives of your father. (Part No. 18; Page No. 354) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
