People who were also traders were also men of Sufism, as we see around Java, people who were outwardly trading but were also men of very high spiritual character. Otherwise no trader would be able to convert a person from one religion to another. It was because they were men of spiritual character.
Seyyed Hossein NasrIf 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.
Seyyed Hossein NasrThe 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.
Seyyed Hossein NasrThere is an idea that you can take the spiritual teachings of a religion outside of a religion and practice them; these ideas are brought forward. That appears to be easy. You can say, "Oh, well. I don't have to bother about not eating pork, and not drinking wine, and all you have to do is read the beautiful poetry of Rumi and talk about wine, women and song. Or something like that." This kind of attitude. This is the antipode of the other attitude which says Islam is nothing but throwing bombs, it has nothing to do with internal or inward purification.
Seyyed Hossein NasrLook at Senegal, about 90% of the Muslims in Senegal are Tijani or Qadiri Sufis. Among them, they have very great teachers who have written poems about al-Hallaj, and they have not been killed. In fact, it's Sufism that brought Islam through all of Senegal, right under our noses the last couple of centuries. And you can go down the same line through Indonesia and Malaysia.
