So Islam claims to be connected to the bible(both old and new testament).

3 Requirements are required.
1. Bloodline, the connection to the jewish people or as the bible believes(until Jesus) god's "chosen ones". Jesus was linked to david and abraham, there fore christianity has this connection.
[X] No bloodline connection from Islam.

2. Same doctrine.
[X] Nope. Islam neither follows the system Jesus set up nor the traditional Jewish system. Almost none of the laws are the same, there is no need for sacrifices or Jesus's "forgiveness".

3. Same god.
[x] Islam's god shares none of the same tendencies or actions that the jewish or christian god exhibits. He does not use hellfire, nor does he preach forgiveness/peace/tolerance.


So if anyone ever tells you "Islam is part of X" tell them to shove it up their ass.

Just some pre-emptive responses:

No, the bible was not "corrupted" or whatever.

Even if it was, claiming to be part of a corrupted source would make you corrupted by default.
