In The Qur'an
The word Injil occurs twelve times in the Qur'an and refers to the Book of revelation given to the Prophet Jesus. Muslim scholars generally agree that Injil refers to the true Gospel, bestowed upon Jesus by God. The word Injil is used in the Qur'an, the Hadith and early Muslim documents to refer specifically to the revelations made by God to Jesus. Muslims reject that Jesus or any other person wrote the Injil, instead crediting its authorship to God. Many Muslim scholars believe that the Gospel has undergone alteration, that the words and the meaning of the words have been distorted, with some passages suppressed and others added. The Islamic principle of the oneness and wholeness of God's divinity means that in their view it is impossible for Jesus to be God incarnate or the Son of God, and that the worship of Jesus by Christians is due to later additions. The Qur'an says of the Gospel:
"And We sent in their footsteps Jesus, son of Mary, authenticating what was present with him of the Torah. And We gave him the Gospel, in it was a guidance and a light, and authenticating what was present with him of the Torah, and a guidance and a lesson for the righteous."
The Qur'an further describes the followers of the Gospel, that is the Christians, in a highly positive allegory, saying:
"Muhammad is the messenger of God, and those who are with him are severe against the rejecters, but merciful between themselves. You see them kneeling and prostrating, they seek the blessings and approval of God. Their distinction is in their faces, as a result of prostrating. Such is their example in the Torah. And their example in the Gospel is like a plant which shoots out and becomes strong and thick and it stands straight on its trunk, pleasing to the farmers. That He may enrage the rejecters with them. God promises those among them who believe and do good works a forgiveness and a great reward."
