Why Jesus was born as faultless son and why not Mohammed?

In Islamic belief, Jesus (known as Isa in Arabic) is regarded as a prophet and messenger of Allah who was born without a father, a miraculous event that signifies his unique status. The Qur'an states, Such was Jesus, son of Mary: (this is) a statement of the truth concerning which they doubt. 19:34. This highlights Jesus' extraordinary birth, which serves as a sign of God's power to create without the usual means.

The Qur'an also emphasizes Jesus' role as a messenger and a servant of Allah. In Surah An-Nisaa, it states, The Messiah, Jesus son of Mary, was only a messenger of Allah, and His word which He conveyed unto Mary, and a spirit from Him 4:171. This indicates that while Jesus has a unique and exalted status with a miraculous birth, he is still one of many prophets sent by God to guide humanity.

On the other hand, Prophet Muhammad (peace be upon him) is considered the final messenger in Islam, sent to convey the complete message of Allah to humanity. His birth was normal, yet he is highly revered for his character, prophethood, and the message he delivered. The concept of Muhammad's prophethood does not require a miraculous birth, as he is seen as a model for humanity, embodying moral and ethical perfection through his actions and teachings.

As for the notion of being "faultless," Islamic tradition holds that all prophets are protected from major sins and errors in delivering their message. However, they are still human and experience the same trials and tribulations as other people. The distinction lies in their roles and the specific divine missions they were given.

In summary, Jesus' miraculous birth signifies his unique role as a prophet, while Muhammad's role as the final prophet exemplifies the culmination of divine guidance to humanity. Both hold significant places within Islamic theology, yet their statuses reflect different aspects of God's will and purpose in prophethood.
