Al-Ma'idah · 5:82

82. You will find, O Messenger, that the people with the most hostility towards those who have faith in you and that which you brought are the Jews, due to their malice, jealousy and pride, as well as the idol worshippers and others who associate partners with Allah. You will also find that the people who are closest in affection to those who have faith in you and that which you brought are those who call themselves Christians. The verse explains that the reason for these people being close to the believers is that there are scholars, ascetics and worshippers among them who are humble and not proud. Good does not enter the heart of a proud person.
