Did Jesus' disciples follow Islam and consider themselves Muslims?

In the book of Acts, the apostles, particularly Peter, testify to the crucifixion and resurrection of Jesus, declaring Him as both Lord and Christ. This proclamation highlights that they were witnesses to His mighty works and the fulfillment of prophecies concerning the Messiah. Peter's assertion that Jesus has been exalted to the right hand of God and has poured out the Holy Spirit upon His followers underscores the unique Christian belief in Jesus' divinity and authority, which contrasts sharply with Islamic views of Jesus as merely a prophet. Furthermore, the disciples' message of salvation through faith in Jesus' name is a central tenet of Christianity that is not found in Islam, where the concept of salvation is based on works and adherence to the teachings of Muhammad. Thus, the claim that the disciples were Muslims misrepresents their beliefs and the foundational truths of Christianity.
