What is the ruling on one who disregards the unanimously agreed upon interpretations of the exegetes and denies many of them, and is he thereby considered a denier of the Qur’an?

The texts of the Qur’an, the Sunnah, and the consensus (ijma') are definitive regarding the disbelief of the Christians who did not believe in Muhammad (peace be upon him), or who associated partners with Allah, or who denied the prophethood of a prophet. Their religion is rejected, and they are losers. As Allah Almighty says: "And whoever desires a religion other than Islam, it will never be accepted from him, and in the Hereafter, he will be among the losers" (Quran 3:85). And whoever said that Allah is the Messiah, son of Mary, has disbelieved, as has whoever took their rabbis and monks as lords besides Allah. The People of the Book and the polytheists are disbelievers until clear evidence comes to them. And whoever disbelieves in Allah and His Messengers and wishes to differentiate between them is truly a disbeliever. One must be wary of the nullifiers of Islam, which include stating that the polytheists are not disbelievers, or doubting that, or validating their creed; whoever does that is a disbeliever.
