How do I purify haram investment gains?

By Mehdi, Senior Sukuk Fund Manager · Updated May 2026

Purification sounds technical and frightening, but the idea behind it is simple and merciful: you do not have to throw everything away because part was tainted. You remove the tainted part, and keep the rest with a clear heart.

The short answer: Purification means working out the portion of your returns that came from impermissible sources — and giving exactly that portion away, seeking no reward for it. It cleanses what was not yours to keep, so the rest of your wealth stays clean.

The impermissible portion usually comes from two places: interest a company earned on the side, and any income from a slice of its business that was not permissible. Many screened funds publish a purification figure each year — the share of returns you should give away — precisely so you do not have to calculate it yourself.

The intention matters as much as the act. This giving is not sadaqah you are rewarded for, because it was never your clean money to begin with. You give it to remove it, quietly, expecting no reward — and what remains in your hands is then clean. That distinction protects you from a subtle trap: treating cleansing as if it were generosity.

Find the impermissible portion — use the fund's published purification figure, a screening tool, or a scholar's estimate.
Give exactly that amount to those in need, seeking no reward for it.
Keep a simple record, holding by holding, so you know it is done.
Going forward, hold screened investments so there is little or nothing left to purify.

There is something freeing in this. You are not asked to be perfect — you are asked to be honest and to clean what you can. Allah is Al-Ghafoor. Purify what slipped through, and let your heart rest.
