Nikaah & Marriage IssuesThose women with whom nikaah is permissible

Question

I am writing to seek your guidance on a family matter concerning marriage eligibility in Islam.

I am considering the possibility of proposing marriage between my daughter and her first cousin from mother side. However, there is a specific detail that we need to clarify: the boy's younger sister is also our daughter's radaai sister (sister through breastfeeding).

Given this relationship, I am unsure if it is permissible for my daughter to marry her cousin. Could you please provide clarity on this matter according to Islamic principles?

Answer

Nikaah between the both is permissible. The boy's younger sister being the foster-sister of the girl will not affect the nikaah in any way.

And Allah Ta'ala (الله تعالى) knows best.
