Europeans are the descendants of Rūm aka Rome named after the Roman Empre. If you look at the image in the original post, Sayid Ayūb AS was a direct descendant. They were nicknamed Banu Asfar for their Yellow skin and blonde hair.
how can europeans be from rum when the romans were fighting different people across europe with different languages and skin colour, blonder with bluer eyes?
just say the romans are one of the groups of europe, the romans were part of the latini people, even italy before roman times had many many languages and tribes who hated each other
but to say all europeans are from Rum, is like saying in today all Africans are descendant from nigeria, when nigeria herself is one of the many nations across africa, i hope you get my gist old chap,
