Endogamy is one of the practices that took root in Indian society as a way to enforce the caste system. Some scholars even call it the rationale behind the caste system. It’s got it’s roots in Hindu scriptures (not hating on the religion, but it does need reformation IMO).
P.S I think proximity to India, trade with India could have lead to the practice being observed in Afghanistan, but it also seems like Islamic clergy (majority practice this in Afghanistan) does not have entirely progressive views on this.
