Islam, in contrast to Christianity and Buddhism, does not have monasticism; spiritual life, social life, they are all integrated and related together in one way or another. And the Prophet represents that in his life.

There are millions and millions of Sufis who have existed in Islamic history and have the deepest impact on every aspect of Islamic culture and civilization to philosophy to art to science to social structure to economics who have not met the destiny of al-Hallaj.

Spiritual guidance needs guidance. It's like comparing walking on the ground and mountain climbing. Once you learn how to walk, you can walk on the ground by yourself, but if you want to climb Mount Everest, you need a guide.

Sufis have always been those that have tried to purify the ethics of Islam and society. And they don't have their hands cut off from the external action at all. For example, the bazaar in which the Sufis were very strong always dominated economic life in Islamic world. They could give a much more sane and Islamic form of activity when the economic life of Islam moved out of the bazaar to new parts of Islamic cities with modernized Muslims, who took it in another light and it became very, very anti Islamic, and much against many of the most profound practices of Islamic societies.

The Quran explicitly opposes the killing of innocent people and the Prophet was always careful in doing that. If they had to fight a war, he was always on the side of peace as soon as it was possible to make peace because that's what the Quran says also.

Muhammad was, first of all, a Prophet of course, a beloved and lover of God, a father, an army commander, a judge, a ruler of a community, the King of Medina and later of Arabia, and all of these were combined in him and his destiny, the reason God brought him on earth, was to show how each of the functions which human beings have in life have the perfect form in the prophet.

What does a lamp do? The lamp is like a horse that is running but stays put. But by virtue of being a lamp it illuminates the space around it. Therefore, the practice of purifying one's soul, of living virtuously, has tremendous impacts upon the ethics of the surrounding society.
