while outwardly he had to face nearly every possible human situation. He experienced being an orphan, living the life of a merchant, suffering persecution. He grieved deeply the loss of his beloved wife Khadījah and his two-year-old son Ibrāhīm, but he also knew the happiness of family life and of final triumph in the world. He, who loved solitude and contemplation, had to deal with the affairs of men and women, with all their frailties and shortcomings. He had to rule over a whole society and to sit as judge in cases of one party's complaints against another. One might say that his mission was to sanctify all of life and to create an equilibrium in human life that could serve as the basis for surrender and effacement before the Divine Truth.-Seyyed Hossein Nasr, The Heart of Islam: Enduring Values for Humanity, p. 34.
