Instead, wealthy and pious Shias chose to give financial contributions directly to the leading ayatollahs in the form of zakat, or obligatory alms. The clergy, in turn, used the funds to administer their madrassas and to institute various educational and charitable programs, which indirectly provided them with more influence in society. The access of the clergy to a steady and independent source of funding was an important factor in their ability to resist state controls, and ultimately helped them direct the opposition to the shah.[1]
