If a person is given a chance to examine the biography of Prophet Muhammad comprehensively from all aspects, while breaking free from the fetters of personal bias, he will definitely conclude that such a great man cannot be but a Prophet who received revelation and a Messenger from the Lord of the Worlds.
This comprehensive examination can be done by two means:
First: A detailed exploration of his biography, probing into his life at times of peace and war, prosperity and distress, health and sickness, residence and travel, his private domestic life and public social life ... etc.
Whoever probes deeply into these vital aspects of his life, assuming the role of a vigilant observer while considering the subsequent events, will inevitably conclude his Prophethood and deduce that he was not merely a great man but rather a Messenger of Allah entrusted with the divine revelation.
