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.

Muhammad was the exemplar ruler, exemplar father, exemplar warrior, and once you have a family, you have contentions, you have problems, human problems, and it's the human order. He set the example and model for Muslims for all the different endeavors. He is not only the example of the spiritual life, but he is also an example for our life in this world.

If you have a billion Muslims, 900 million of them were not brought into Islam by any kind of invasion, but most of them through the Sufis, because human beings are such that they are affected by people of spiritual character. Certainly when they display nobility and hospitality and gentility and love and are not selfish or aggressive, and they are honest.

Why does one need a doctor if God has given us our body and we pray to Him for our help?

If you want to make a decision in life on what to do, but if you're trying systematically, through spiritual practice, through meditation, through the invocation of the name of God, to walk closer and closer in this life to Him, you need someone to guide you. And God has made it possible in Islam for this guidance to exist.

Jalaluddin Rumi is completely rooted in Islamic teachings of Quran. He was a great scholar, he belonged to a madrassa, and he knew Islamic theology and jurisprudence very well. He knew Persian, Arabic and Turkish, which was coming into Anatolia at that time, very well. He was a remarkable, remarkable scholar, besides being a great saint.

300 years after the rise of Islam there were Zoroastrians in Iran. The Muslim armies never forced people to accept Islam. It was only within Arabia that God ordered the idolaters to have a choice of either embracing Islam or fight against Muslims, because He wanted to remove this terrible idolatry that exited there. But outside Arabia where Islam met Christians, Jews, Zoroastrians and Hindus, they were given a choice by and large. That's why many Christians and Jewish communities survived in the Muslim world, but gradually many of them embraced Islam for different reasons.
