O Prophet, We have sent down this Quran to you (similar to that of Musa and Isa). So the People of the Book believe in it, and so do some of these (people of Arabia): and none but ˹stubborn˺ unbelievers deny Our verses.
Meaning:-
Stubborn: is very unwilling to change their mind, unwilling to change ideas or be influenced; very difficult to change or to defeat.
