You ignored my question, thats fine. Look i'm not saying you should marry your cousin, im saying you can and this suugo science about disabilities is bs. Allah only makes halal that which is good and pure for us. Becareful not to repeat things the gaalo say that contradict Allahs word
the Prophet himself (peace and blessings be upon him) married his first cousin, Zaynab bint Jahsh (Allah be pleased with her), as she was the daughter of the Prophet’s paternal aunt Umaymah.
Of course, the permissibility does not necessarily mean that such marriages are encouraged in the Sacred Law, especially when repeated over generations. As mentioned above, there are often health concerns if first cousin marriages continue over several generations. A physician should be consulted in particular cases.
