What are the proofs of God's existence and His oneness, and how do we respond to the claims of the West that the Prophet (peace be upon him) innovated the Qur'an, and what is the proof that the Qur'an has not been falsified, and how do we prove that the Prophet did not write it, and what is the comparison of religions that confirms Islam is the true religion?

The existence of the Creator is ingrained in human nature, and the proofs of His existence are evident in the order of the universe and humanity. As for the existence of one God, without any partner, this is because a multiplicity of gods would lead to chaos in the universe and conflict among them. Do not pay attention to the words of the disbelievers regarding the message of Muhammad, peace be upon him, for the prophets before him foretold his coming. Whoever does not believe in him is a disbeliever, eternally in Hellfire. The Qur'an is an enduring miracle; its eloquence, its truthful prophecies, and its scientific facts prove that it is from God and preserved from alteration. The whispers that may assail you are from the wiles of Satan, and repelling them is a clear sign of faith. Islam is the religion that God has approved, and whoever dies upon other than it is a loser. It is obligatory to seek deep understanding in the religion.
