It's barawani or barawi* Barwani is an Omani tribe . No evidence for that waffle you made up, DNA varies from tribe to tribe so be specific which barawani tribes you're talking about, there's barely been enough barawanis that tested from all tribes to come to such conclusionsBarwanis don’t have much Arab blood, they mainly carry Indian, Persian & Bantu blood mixed in with Somali.
Northern Somalis have Arabian admixture mainly from pre-Islamic times.
Arabian ancestry is fine because they’re fellow Afro-Asiatics. South Asian, Central Asian, Persian & Bantu dna e.g are alien to Somalis.
