Islam is the religion that Allah Almighty revealed to His Prophet and Messenger Muhammad bin Abdullah, peace and blessings be upon him when the Qur’an descended upon him confirming what is in the Torah and the Gospel. It is Heaven’s final and comprehensive message for what is good for man, in this world and the Hereafter, until the Day of Judgment. Allah sent Muhammad, peace and prayers, messengers of the world, and did not send him to his Muslim people only. Coexistence in Islam is based on a belief base and is rooted in faith. Therefore, the concept of coexistence from the perspective of Islam is not among the modern positivist concepts from which the rules of international law were formulated. The Muslim believes that divine guidance came through a long series of messages and prophecies, the last of which are Judaism, Christianity, and Islam. It is therefore natural that these three religions are closer to each other than they are to all other religions, and the Qur’an calls Christians and Jews (People of the Book), because Allah Almighty revealed the Torah to Moses and the Gospel to Jesus, peace be upon them, before Muhammad, peace, and blessings are upon him, received the message in its completeness, confirming what was before it, correcting and detailing matters of Sharia and law beside worship and morals. So, the Noble Qur’an was revealed, and it is the only one remaining in its original language.
