Who is Jesus in the Koran?
We have learned that the Koran is the religious book of Islam with 114 revealed and increated suras: it contains the word of God through a kind of supernatural dictation which is the revelation of Allah to Mohammed, the last of the prophets, through the Archangel Gabriel /Jibril / Spirit of God). Jesus (Aïssa, Eisa, Yeshoua, Yeshoua, Yssa (the spirit of Allah), AL-masîh (the messiah), Nabi (prophet),...) is the only prophet to be born of the divine word, therefore followed by his verb (logos). Without paternal filiation and of any division like the Holy Trinity in Christianity, he is given a very high stature before God.

His birth:
Namely, in the Koranic texts, Jesus has different names: Ibn Maryam (son of Mary); Min al-muqarrabîn (among relatives), wajîh (worthy of consideration), mubârak (blessed), qawl al-haqq (word of truth), Abd Allah (servant of God), Rasûl (sent, messenger), etc.

Mary, a virgin, therefore became pregnant with Jesus, and when the time came to give birth, she moved away from her family and headed for the East.  At the foot of a date palm, she gave birth to her son. Sura 19:19, Gabriel said to Maryam: "I am in fact a messenger of your Lord to give you a pure son. "Jesus was born miraculously on God's command, just like Adam, whom God had breathed life into without having a father.  God said, "Be"; and he was. (The same goes for the child of Mary - Qur'an, 3:47- Course reference). Jesus spoke from birth and it was around the age of thirty that he began his mission. It should be noted that in Sura 19 there are some similarities close to the Christian faith such as: the Annunciation, the coming of the Spirit of God, the virginal conception of Jesus,... (Points developed in Mary in the Quran)

His mission:
The Qur'an teaches that Jesus, prophet and emissary of God, is blessed with gifts from God such as the gift of performing miracles (Bayyinât) (2.87; 5.110; 43.63; 61.6). His natural powers give him the legitimacy of his divine mission to his people. However, the majority of Jews refused to believe in his prophetic mission.

Sura 3:48-49: "And (Allah) will teach him the Scripture, the Wisdom, the Torah and the Gospel, and he will be the messenger to the children of Israel,[and will tell them]: "Verily I come to you with a sign from your Lord. For you, I form clay like the figure of a bird, then I blow into it: and, with Allah's permission, it becomes a bird. And I heal the blind-born and the leper, and I raise the dead, with Allah's permission. And I teach you what you eat and what you collect in your homes. "It should be noted that in Jesus' time, the Israelites were very knowledgeable in medicine.  Therefore, the miracles performed by Jesus (with God's permission) were of this nature and included giving sight back to the blind, healing the lepers and raising the dead (Sura 5:110).

Jesus removes some prohibitions "I have come to confirm what existed before me of the Torah and to make you lawful some of the things that have been prohibited to you. I have come with verses from your Lord. Fear God and obey me. "(3:50), and he announces above all the coming of the Paraclete: his natural successor Muhammad (61:6):"... Jesus, son of Mary, says:" O children of Israel!  I am truly the messenger of God, who is sent to you to confirm what has been (revealed) before my coming in the Torah, and to preach to you the good news of a messenger who will come after me and whose name will be "Ahmed".

His preaching: Monotheism - Obedience - Well-foundedness
Islam categorically refutes the concept of the Trinity, because "only God deserves worship". The slightest cult dedicated to anyone other than Him being considered as Idolatry or Association is the greatest sin in Islam, it cannot be forgiven. Thus in Sura 5 Al-Mâ-Idah (The Table Served), God asks Jesus and Mary himself, to know if the two beings have asked to be associated with God in place of Him Alone, 72-73. There is only One Divinity in the Koran. We note that Allah has no children. Jesus cannot be worshipped as God. Believing in the Trinity is being polytheistic (112.4 And no one is equal to Him)-Then comes faith, it is believing that Allah exists, being grateful to Him and obeying His commands. (2,177)

His death, what does Islam say?
Many commentators attempted the Koranic exegesis of the verses relating Jesus' last moments on earth, but it is clear that the deep meaning of these verses is still mysterious. Whether Sunni or Shia (note that according to the course, some Shia currents, philosophical (platonic) and mystical, will admit that Jesus' body is on the cross, but that his soul has been raised to heaven - see M. M.Hayek, Christ of Islam, 227-236), the vast majority of Muslims approve the Koranic account that Jesus was never put to death or crucified by the Roman authorities and the Israelites, but only "recalled" to his Lord. For God, in his majesty, could not allow such an act against his envoy. The Koran states: ...They said: "We killed the Messiah, Jesus, son of Mary, the messenger of God"... Now, they neither killed him nor crucified him, but his appearance was given to another man /(what man?) and they killed this man... (Qur'an, 4,157) - Also, in the apocryphal gospel/bible of Barnabas is delivered the key to the enigma concerning the death and resurrection of Jesus, which I will develop in The Gospel of Barnabas. God clearly affirms that He raised Jesus to Himself. "...but Allah raised him to Him. And Allah is Mighty and Wise, 4:158" (There is no question of resurrection)

His eschatological role:
According to an eschatological tradition based on Koranic verses whose meaning is surely still esoteric, and above all, on prophetic hadiths, a Messiah (Note that the Koran adopts this title of Jesus without explaining it) "Massih", will return at the end of time to restore the religion of truth. Many of these hadiths affirm that it will indeed be Jesus Christ "Issa". It should be noted that hadiths are "words" and "deeds" attributed to Prophet Mohammed and his companions, these constitute the Muslim tradition, known as the Sunna.

The Prophet Muhammad said to his companions: "Jesus, the son of Mary, will come down among you and judge according to the Koranic law and not according to the law of the Gospel. " (sahih al-Bukhari)In the Qur'an, God reminds us that Judgment Day is a day that no one can avoid and that Jesus' return to earth will be a sign of the imminence of that Day. "[Jesus] will be a sign of the[imminent arrival of] the Hour.  So have no doubt about[the Hour] and follow Me: this is the right way. " (Sura, 43:61)
