Earlier, I demonstrated that prophethood is the only valid and reliable source of knowledge about God, His nature, and His attributes. I also mentioned that any wise person can reach this conclusion by performing an objective analysis. However, not everyone is equally intelligent; therefore, many people cannot do such in-depth analyses. Moreover, some people may require additional affirmation regarding the truthfulness of prophets before making the final decision to believe in them. They are looking for some sort of final sign from God. For such people, God gave His prophets miracles as additional support to recognize their truthfulness. The Holy Quran is a timeless miracle of the last prophet of God, that is Prophet Muhammad PBUH. This miracle can still be witnessed, and it proves the true prophethood of Prophet Muhammad PBUH.
