They will be happy because of the help of Allah being with the Romans due to them being the people of the book. Allah helps whoever He wishes against whoever He wishes; He is the Almighty who cannot be overcome, the Merciful towards His believing servants.
And We did not send any messenger except [speaking] in the language of his people to state clearly for them, and Allāh sends astray [thereby] whom He wills and guides whom He wills. And He is the Exalted in Might, the Wise.
