The Qur'an and the Bible agree that Jesus was special. He is recognised as one 'par excellence' but to understand the whole purpose of his coming one has to study and see him in the light of the Torah, the psalms and the books of the prophets, which Jesus himself referred to. It is through these scriptures that one can see the full picture of Jesus and how his companions and disciples understood him (2 Peter 1:16-17; 1 John 1:1-4). The Qur'an says that Jesus was sent in order to 'make him a Sign unto men' (Surah 19:21). However, the whole story can only be found in the scriptures of those, known to Muslims as ahl al-kitab (the people of the Book) or in today's language, the people of the Bible.
If you wouldlike to know how Jesus is the Sign and Mercy for all humankind, we will be glad to send you a copy of the the New Testament.
