“….one cannot be exempt from Zakat, which is one of the basic principles of Islam, by paying other Chandas. All our success depends upon holding fast to the principals of Islam. …. We must consider the payment of Zakat to be as obligatory as prayer, fasting and performing the Hajj”

– Hazrat Khalifatul Masih I, may Allah be pleased with him, in An Introduction to Financial Sacrifice (pp.84-86)
