Final answer:
The Holy Book revealed to Hazrat Issa (Jesus) is the Injil. While acknowledging Jesus as a prophet, the Qur'an, revealed to Prophet Muhammad, is considered by Muslims to be the final and uncorrupted divine revelation, completing the messages of earlier scriptures.
Step-by-step explanation:
The Holy Book revealed to Hazrat Issa (Jesus) is the Injil (b). In Islam, the Injil is considered to be the scripture given to Jesus by God. The Qur'an, the holy scripture of Islam, affirms the status of Jesus as a prophet and his mother Mary as held in great esteem, but rejects the notion that Jesus was the Son of God and the concept of the Trinity. The Qur'an, which was revealed to the Prophet Muhammad, includes narratives and teachings about Jesus, emphasizing his human nature and his role as a prophet to the Children of Israel.
The Qur'an's contents were revealed piecemeal to Muhammad over 23 years and include chapters that confirm the shared spiritual heritage with Judaism and Christianity. However, the Qur'an maintains that it is the final and uncorrupted version of the divine revelations, completing the messages that were given in earlier scriptures, such as the Tawrat (Torah) given to Moses, the Zabur (Psalms) given to David, and the Injil given to Jesus.
