‘Isa not an historical figure
The Qur’an’s ‘Isa is not an historical figure. His identity and role as a prophet of Islam is based solely on supposed revelations to Muhammad over half a millennium after the Jesus of history lived and died.
Jesus’ name was never ‘Isa
Jesus’ mother tongue was Aramaic. In his own lifetime he was called Yeshua in Aramaic, and Jesu in Greek. This is like calling the same person John when speaking English and Jean when speaking French: Jesu, pronounced "Yesoo", is the Greek form of Aramaic Yeshua. (The final -s in Jesu-s is a Greek grammatical ending.) Yeshua is itself a form of Hebrew Yehoshua’, which means ‘the Lord is salvation’. However Yehoshua’ is normally given in English as Joshua. So Joshua and Jesus are variants of the same name.
It is interesting that Jesus' name Yehoshua’ contains within it the proper Hebrew name for God, the first syllable Yeh- being short for YHWH ‘the LORD’.
Yeshua of Nazareth was never called ‘Isa, the name the Qur’an gives to him. Arab-speaking Christians refer to Jesus as Yasou’ (from Yeshua) not ‘Isa.
Jesus did not receive a ‘book’
According to the Qur’an, the ‘book’ revealed to ‘Isa was the Injil. The word Injil is a corrupted form of the Greek euanggelion ‘good news’ or gospel. What was this euanggelion? This was just how Jesus referred to his message: as good news. The expression euanggelion did not refer to a fixed revealed text, and there is absolutely no evidence that Jesus received a ‘book’ of revelation from God.
The ‘gospels’ of the Bible are biographies
The term euanggelion later came to be used as a title for the four biographies of Jesus written by Matthew, Mark, Luke and John, the ‘gospels’. This was a secondary development of meaning. Apparently this is where Muhammad got his mistaken idea of the Injil being a ‘book’.
Most so-called prophets of Islam received no book
Virtually all of the so-called ‘prophets’ of Islam, whose names are taken from the Hebrew scriptures, received no ‘book’ or law code. For example, the Psalms are not a book revealing Islam, as the Qur’an claims, but a collection of songs of worship, only some of which are David’s. There is not a shred of evidence in the Biblical history of David that he received a book of laws for the Israelites. They already had the Torah of Moses to follow. So David was not a prophet in the Qur’an’s sense of this word. Likewise most of the prophets claimed by Islam were neither lawgivers nor rulers.
Biblical prophecy and Islamic prophecy are not the same thing
The Biblical understanding of prophecy is quite different from Muhammad’s. A Biblical prophecy is not regarded as a passage from a heavenly eternally pre-existent text like the Qur’an, but a message from God for a specific time and place. A biblical prophet is someone to whom God reveals hidden things, and who then acts as God’s verbal agent. When a Samaritan woman called Jesus a prophet (John 4:19) it was because he had spoken about things in her life that he could only have known supernaturally. Christianity teaches that Jesus was a prophet, but he brought no ‘book’: he himself was the living ‘Word of God’, a title used of ‘Isa in the Qur’an.
By no means all prophecies referred to in the Bible became part of the Biblical text. The Bible consists of a wide variety of materials originally written for many different purposes, including letters, songs, love poetry, historical narratives, legal texts, proverbial wisdom as well as prophetic passages. These are regarded as inspired by God, but not dictated from a timeless heavenly book.
As prophetic history, the Qur’an contains many errors and anachronisms
The claim that Jesus was not executed by crucifixion is without any historical support. One of the things that all the early sources agree on is Jesus’ crucifixion.
Mariam the mother of ‘Isa is called a sister of Aaron, and also the daughter of Aaron’s father ‘Imran (Hebr. Amram). Clearly Muhammad has confused Mary (Hebr. Miriam) with Miriam of the Exodus. The two lived more than a thousand years apart!
In the Bible Haman is the minister of Ahasuerus in Media and Persia (The Book of Esther 3:1-2). Yet the Qur’an places him over a thousand years earlier, as a minister of Pharoah in Egypt.
The claim that Christians believe in three Gods — Father, son Jesus and mother Mary — is mistaken. The Qur’an is also mistaken to claim that Jews say Ezra was a son of God. (At-Taubah 9:30) The charge of polytheism against Christianity and Judaism is ill-informed and false. (Deuteronomy 6:4, James 2:19a)
The story of the ‘two horned one’ (Al-Kahf 18:82 cf also Daniel 8:3, 20-21) is derived from the Romance of Alexander. Certainly Alexander the Great was no Muslim.
The problem with the name ‘Isa has already been discussed. Other Biblical names are also misunderstood in the Qur’an, and their meanings lost. For example Elisha, which means ‘God is salvation’, is given in the Qur’an as al-Yash’a, turning El ‘God’ into al- ‘the’. (Islamic tradition did the same to Alexander the Great, calling him al-Iskandar ‘the Iskander’). Abraham ‘Father of many’ (cf Genesis 17:5) might have been better represented as something like Aburahim ‘father of mercy’ instead of Ibrahim, which has no meaning in Arabic at all.
The Qur’an has a Samaritan making the golden calf, which was worshipped by the Israelites in the wilderness (Ta Ha 20:85) during the Exodus. In fact it was Aaron (Exodus 34:1-6). The Samaritans did not exist until several centuries later. They were descendants of the northern Israelites centuries after the Exodus.
Many Qur’anic stories can be traced to Jewish and Christian folktales and other apocryphal literature. For example a story of Abraham destroying idols (As-Saffat 37) is found in a Jewish folktale, the Midrash Rabbah. The Qur’anic story of Zachariah, father of John the Baptist, is based upon a second-century Christian fable. The story of Jesus being born under a palm tree is also based on a late fable, as is the story of Jesus making clay birds come alive. Everything the Qur’an says about the life of Jesus which is not found in the Bible can be traced to fables composed more than a hundred years after Jesus’ death.
Jesus’ titles of Messiah and Word of God, which the Qur’an uses, find no explanation in the Qur’an. Yet in the Bible, from which they are taken, these titles are well integrated in a whole theological system.
The Qur’an mentions the Holy Spirit in connection with Jesus, using phrases which come from the gospels. Ibn Ishaq (Life of Muhammad) reports Muhammad as saying that this ‘Spirit’ was the angel Gabriel (cf also An-Nahl 16:102, Al-Baqarah 2:97). However the Biblical phrase ‘Spirit of God’ (Ruach Elohim) or ‘Holy Spirit’ can only be understood in light of the Hebrew scriptures. It certainly does not refer to an angel.
Jesus’ alleged foretelling of Muhammad’s coming (As-Saff 61:6) appears to be based on a garbled reading of John 14:26, a passage which in fact refers to the Spirit.
The Hebrew scriptures were Jesus’ Bible. He affirmed their authority and reliability and preached from them. From these same scriptures he knew God as Adonai Elohim, the Lord God of Israel. He did not call God Allah, which appears to have been the name or title of a pagan Arabian deity worshipped in Mecca before Muhammad. Muhammad's pagan father, who died before Muhammad was born, already bore the name ‘Abd Allah ‘slave of Allah’, and his uncle was called Obeid Allah.
We read that An-Najm 53:19-23 seeks to refute the pagan Arab belief that Allah had daughters named al-Uzza, al-Ilat and Manat. (See also An-Nahl 16:57 and Al-An’am 6:100).
The Biblical narratives are rich with historical details, many confirmed by archaeology. They cover more than a thousand years, and reveal a long process of technological and cultural development. In contrast the Qur’an’s sacred history is devoid of archaeological support. Its fragmentary and disjointed stories offer no authentic reflection of historical cultures. No place name from ancient Israel is mentioned, not even Jerusalem. Many of the supposed historical events reported in the Qur’an have no independent verification. For example we are told that Abraham and Ishmael built the Kaaba in Mecca (Al-Baqarah 2:127), but this is totally without support. The Biblical account, more than a thousand years older, does not place Abraham anywhere near Arabia.
The Qur’an is not a credible source for Biblical history
The Qur’an, written in the 7th century AD, cannot be regarded as having any authority whatsoever to inform us about Jesus of Nazareth. It offers no evidence for its claims about biblical history. Its numerous historical errors reflect a garbled understanding of the Bible.
