Income Purification

Income purification is the process of identifying income that is not Sharia-compliant — such as interest earned incidentally or the share of a dividend from prohibited activities — and giving it away, usually to charity, instead of treating it as profit.

Also called: purification · cleansing · dividend purification · purification of income

It arises wherever complete avoidance is impractical. Sharia-compliant equity funds usually screen companies by their business and by financial ratios, then accept that a company may still earn a small amount of interest or prohibited revenue. The proportion of each dividend attributable to that income is calculated and paid out. Islamic banks do the same with income from a transaction later found to be non-compliant, and with late-payment charges.

The purified amount must leave the institution or investor entirely, normally to a charitable channel approved by its Sharia Supervisory Board, and must not be used to benefit the person purifying it — for example by paying their own expenses or taxes.

In practice

Purification does not make a prohibited business acceptable. It is a remedy for incidental non-compliant income in an otherwise permissible investment, not a licence to hold non-compliant assets.

Example

A fund receives a US$100,000 dividend from a company that earns 3 per cent of its revenue from interest. The fund calculates US$3,000 as non-compliant, pays it to an approved charity and distributes only US$97,000 to investors.
