Zakah — a fixed, obligatory annual charge on qualifying wealth above a minimum threshold (nisab) — is one of the five pillars of Islam, placing giving on the same footing as prayer and fasting rather than treating it as optional generosity.

The Qur'an consistently pairs zakah with prayer as a marker of genuine faith, and promises that those who establish both prayer and zakah 'will have their reward with their Lord, and there will be no fear concerning them, nor will they grieve.' Financially, it functions as a wealth-purification mechanism — redistributing a small, regular share of accumulated wealth to those in need rather than letting it sit idle indefinitely in a few hands.

Because the calculation depends on your specific savings, assets, and local nisab values, this app has a dedicated Zakat guide and calculator — use it directly rather than estimating from general principles here.
