There is no religion in the world where there is a possibility of spiritual development outside of the context of that religion. This is only a modern invention. For example, Christian mystics were also Christians. They also went to Church and followed Christian laws. Hindu mystics were practicing Hindus; they didn't kill cows and have steak. They follow the Hindu laws and so on and so forth down the line and Sufism is no exception.
Seyyed Hossein NasrTariqah [The Spiritual Path] without the Sharia [Islamic Law] is like having a pistachio tree without the shell. Or a walnut, a walnut cannot grow on a tree without having a shell, and the food that you eat is inside the shell.
Seyyed Hossein NasrMilitarily, the great movements of resistance against colonial powers in the 18th and 19th century were almost all from Sufis: Imam Shamil in Caucasia, Amir Abd al Qadir in Algeria, The Barelvi family in the modern province of India, today which is Pakistan, and you can go down the line.
Seyyed Hossein Nasr300 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.
Seyyed Hossein NasrWhat is tragic today is that there is a number of Muslims who think that all the solutions are to be found simply by external actions. They don't have to do anything within themselves. This is a deeply Western idea - modern, Western idea, where you try to improve the world without improving yourself. And this is what the Muslims who talk about others putting their heads in the sand and that "We are doing jihad and we are political" and so forth, they are emulating a very important mistake of modernism.
