Islam professes to be a restoration of the true Abrahamic religion. It claims that Abraham, Moses and Jesus were all Muslims who merely taught submission to Allah.
It claims that Jews and Christians all distorted the revealed books of Allah (Torah, Psalms, and Gospels).
-Muslim apologists justify this by mentioning the non-canonical books e.g. Gospel of Barnabas, The Shepherd of Hermes.
-Also by finding similarities in early Christian sects e.g. Arianism (rejects the Christian Trinity).
Furthermore they claim that Jews defiled the biographies of the Prophets by insinuating that they committed major sins e.g. King David committing adultery.
-They also claim Jews defiled God’s character e.g. God commanding the killing of the Canaanites which included women and children.
-They reject the Jewish claim that God is a Father; they see their relationship with him as Master and slave.
As for Christians they claim we inserted pagan beliefs e.g. Trinity.
-They claim Christians commit idolatry: praying to Mary, and the saints. Also by having pictures, icons, statues of them.
-They claim the sacred mysteries of our Christian faith are illogical (Jesus’ hypostatic union fully God and fully man). They claim we made Christ divine, he never utter the words “I am God”.
(Defense for sharia). Muslim apologists justify the use of capital punishment in their religion by finding similarities in the OT when God commanded the nation of Israel to execute severe sentences for sinners e.g. stoning adulterers.
(Defense for jihad). Muslims apologists defend Muhammad military campaign as one in line with OT kings, and prophets e.g. King David, Moses.
(Defense for polygamy). Muslims assert that because revered people in the OT were allowed to have multiple wives Muhammad continued on with that practice.
***While I reject Muhammad’s prophethood. I understand that he’s a social reformer. I believe he was successful in creating a great religion based on the precepts of both Jewish and Christian teaching. My narrative is a reconciliation between Islamic, secular, Jewish and Christian sources. At some point in Muhammad’s life he came in contact with Jews and Christians. He admired what he saw in both respective communities. He sought to bring that same stability, uniformity and peace with his own people the warring Arab tribes of his time. Unfortunately for Muhammad his people were not interested in his new message. They were set in their old ways. Eventually Muhammad realize that he would need to claim the title of prophet in order to gain legitimacy for his actions. He sought to find common ground with Jews and Christians. Both would reject granting him this status. Nonetheless Muhammad would continue to win converts, and eventually land as well.
Islam is successful because it has enough truth to attract people to it. e.g. monotheism, 99 names of Allah, reward & merit. It’s also filled with tremendous falsehoods e.g. denial of Christ’s divinity, death, and resurrection. Islam basically makes religion simple it negates all mystery of the faith and simply asks its members to submit to Allah and perform certain exercises to appease him e.g. hajj, charity. Islam will continue to show its might on this world because like Christianity it’s a universal faith. And like Judaism it employs severe punishments in order to keep uniformity in it’s stringent teachings.***
