It’s better for wives of true adherents of Islam not to appear at entertainment events and not to show their charms to the public.
We don’t know anything about Khabib Abdulmanapovich Nurmagomedov’s wife (unlike Dustin’s wife). Only from Habib’s interview, his wife takes care of her children and prefers home comfort. She also honors her faith. Perhaps, participating in MMA, Khabib violates the traditions of Dagestan people, but it is another question.
