Imam Khomeini once in a historic message in this regard said as following:
"I have repeatedly said that this spiritual transformation witnessed in Iran brought about by this Revolution with the will of God, the Most Exalted, the Most High, has been more valuable and more important than the victory we have achieved or the fact that we have curtailed the hands of the foreigners and criminals from this country."

Imam expalined that all monotheistic schools of thought, in action with Islam, as the superior one, are seeking to train people in such a way that material gains do not act as obstacles for spirituality, although they (the divine religions) are involved with materiality as well.
