Now what's interesting about this, this has a lot of parallels with the five times a day prayer of the Zoroastrians, including the ritual washing of your body before each prayer. Now the third pillar is charity, and it's called zakat. And this is customarily 2.5% of wealth. Now 2.5% might not sound like a lot, but this isn't of income, this is of wealth. The fourth pillar is the notion of fasting dawn to dusk during the ninth month of the Islamic calendar, and that month is Ramadan. And it's fasting without food or water, once again, from dawn to dusk. And the Islamic calendar is a lunar calendar.
