Incidents and situations from the Prophet's life are real life lessons to help us. Seerah is more than studying biography of a person, it is biography of our most beloved's life and the history of our religion. Michael Hart wrote a book called "The 100: A Ranking of the Most Influential Persons in History" and he listed Muhammad S as number one. Of course this ranking means nothing to us, we already know without a doubt that our Rasul cannot be compared to any other human. But it just shows that even Non Muslims who have truly studied the seerah admit without hesitation that his life was the best life.
