Jesus' disciples were Muslims because they referred to themselves as such in the Quran.

The Quran claims that Jesus' disciples identified as 'muslims,' implying they adhered to the same beliefs as Muhammad. However, this interpretation overlooks the historical context and the distinct theological differences between Christianity and Islam. The disciples preached that Jesus was the Son of God who died for humanity's sins and rose again, which directly contradicts Islamic doctrine that denies Jesus' divinity and crucifixion. Furthermore, the Quran's assertion that Muhammad came to confirm previous scriptures is problematic, as it suggests that the teachings of the disciples align with Islamic beliefs, which they do not. Therefore, if the Quran were correct, the disciples would not have preached the core tenets of Christianity, such as the Trinity and the resurrection, which are central to the faith.
