Answer: The perfect human, from the Quranic perspective, is one who embodies divine ethics, fully manifests the beautiful names of God, and is a complete reflection of the divine. This person is characterized by virtuous speech, actions, and morals, and is considered the primary reason for creation and the sustenance of the universe. They serve as a guide for others, both outwardly and inwardly, understanding human spiritual maladies and knowing how to heal them, and have attained unity with the divine identity. The prophets and the 14 infallible personalities are the perfect and the best human beings.
In simpler terms, a perfect human is one who has reached the ultimate level of human capabilities in all aspects and has developed all Quranic criteria within themselves. The clear examples of such perfect humans in the Quran are the divine representatives, including prophets and the Imams (peace be upon them).
