Islam is not a new religion, but a re-presentation of the same message and guidance that Allah revealed to all of His prophets. In Qur’an (3:3), we read:
Say, we believe in Allah and that which has been revealed to us, and that which was revealed to Abraham and Ishmael and Isaac and Jacob and the tribes and that which was given to Moses and Jesus and to other Prophets,
from their Lord. We make no distinction between any of them, and to Him we submit.
The message revealed to Prophet Muhammad is Islam in its comprehensive, complete, and final form.
