The opinion of the Holy Quran about Christians

At the bottom are three verses of Surah Ma’idah.

Those who say: GOD is one of the three (disbelievers), surely they disbelieve, and there is no deity except Allah. And if they disobey what they say, it will certainly be a painful retribution for those who disbelieved. (73)

Do they not turn to God, and ask forgiveness of Him? And God is Forgiving and Merciful. (74)

Christ, the son of Mary, is nothing but a messenger before him. And his mother was a very honest woman. Both [like other humans] ate. Consider how we explain the signs to them [to know that those who are born and need food are not God]; Then look at how they deviate [from right to wrong]. (75)
