The disciples of Jesus were Muslims who believed in Allah and recognized Him as the only God.

The Quran asserts that the disciples of Jesus identified themselves as Muslims, suggesting that they adhered to Islamic beliefs. However, the teachings of Jesus and the accounts of His disciples in the New Testament reveal a different narrative. The disciples recognized Jesus as the Son of God and proclaimed His divine authority, which stands in stark contrast to the Islamic view of God’s oneness and the rejection of any partners in His dominion. Furthermore, the Quran explicitly forbids the worship or service of anyone other than Allah, which would include the disciples' identification as 'slaves of Christ.' This concept is fundamental to Islamic theology, which emphasizes the absolute oneness of God and prohibits any form of servitude to others. The disciples' commitment to Jesus as their Lord and Savior indicates that they did not adhere to the Islamic understanding of monotheism. Additionally, the Quran's insistence on the uniqueness of Allah and the denial of Jesus' divine sonship implies that the disciples could not have genuinely claimed to be Muslims while simultaneously proclaiming Jesus' divinity. The early Christian proclamation of Jesus as Lord and the Son of God directly contradicts the assertion that they were Muslims, as such a belief would undermine the very essence of their faith and teachings.
