“When Muhammad linked the name of Allah to the religious histories of Judaism and Christianity, this was a way to claim them for Islam. In the light of later events, the claim that Islam was the original religion, and that all preceding prophets were Muslims, can be regarded as an attempt to appropriate the histories of other religions for Islam. The effect is to rob Christianity and Judaism of their own histories.”
“Consider that many Biblical sites, such as the tombs of the Hebrew Patriarchs and the Temple Mount, are claimed by Islam as Muslim sites, not Jewish or Christian ones. After all, the Qur’an tells us that Abraham ‘was a Muslim’. Under Islamic rule all Jews and Christians were banned from such sites.”
In truth even that is an error because Islam was only around from the 600’s and not before. Even Abraham cannot even be called a Muslim because his faith in God and not in a religion.
It made Islam look more like a lie because it was around from the 600’s.
