 Because obviously within our religion it's okay to intermarry within cousins. He's asking due to genetic problems with marrying cousins, is it better to marry outside of the family or within the family? Well, you look in the life of the Ahlul Bayt Alaym As-Salam and you'll find, for example, Rasulullah sallallahu alayhi wa alayh, one of his marriages is with a cousin and that is Zaynab. Whereas another of his marriages, for example, is with someone like Seyda Khadija, who's not a first cousin. Imam Ali ibn al-Mital alayhi sallam marries his second cousin whereas Seyda Zaynab marries her first cousin. So it's not a rule that you have to marry your first cousin. If you find that there's going to be a medical issue in the family, if you are going to continue to marry cousins, your dad married a cousin, your uncle, your granddad married a cousin, if you could see there's going to be a medical issue then you should not. You should not. Insha'Allah.
