You know that moment. You log into your bank app, and there it is — that sneaky little line that says interest earned: $38.70. Your heart skips. Part pride, part guilt. Pride because hey, free money. Guilt because you know it is riba.
So what do you do if money you believe is impermissible interest enters your account? The first step is to distinguish the source carefully. Ordinary bank interest, investment income that needs purification and CPF interest are not automatically the same religious category. MUIS has specifically ruled that CPF interest is not riba, while its investment guidance explains that non halal portions of mixed investment income should be estimated and given away.
Here are some witty yet practical ways to make riba money count, not for you, but for good.
1. Do Not Treat Disposal as Sadaqah for Reward
Classical and contemporary scholars commonly distinguish between giving lawful charity from your own wealth and disposing of money you should not personally benefit from. The purpose of disposal is to remove the impermissible amount from your ownership, not to turn it into a source of personal religious reward.
2. Do Not Assume Mosques Automatically Reject Purification Money
MUIS guidance on Shariah screening says that when an investor estimates a non halal portion of investment income, that amount should be deducted and donated to Islamic charitable organisations such as mosques and institutions. That does not mean every donation channel will process every type of payment in the same way, so check with the receiving organisation if you are unsure.

3. Community fixes that no one funds
Scholars differ on some details of where impermissible money should be disposed of. Public benefit and assistance to people in need are commonly discussed destinations, while MUIS specifically mentions donating purified non halal investment income to Islamic charitable organisations. Follow reliable guidance for the particular money you are dealing with rather than improvising a beneficiary because it feels charitable.
4. Education without the strings attached
Money being disposed of can be directed to genuine public or charitable benefit according to the scholarly guidance you follow. If you are unsure whether a particular beneficiary or religious institution is appropriate, ask the institution or a qualified scholar before transferring the money.
5. A witty reminder on what not to do
Please, do not buy yourself that smartwatch and call it “cleansing the riba.” That is just wishful accounting. And no, paying off your own parking fines does not count either. If you want to feel better, channel it outwards, not inwards.
Why bother if Allah might not accept it?
Because here is the deal, only Allah knows what is accepted. You are not “purifying” yourself with riba money, you are simply making sure it does not taint your lifestyle. It is like putting the trash in the bin instead of keeping it on your sofa. You know which is the better choice.
And for those who ask, “But what if I just want it?”
If you have confirmed that an amount should be removed, do not delay simply because the sum feels small. Calculate it carefully and dispose of it according to the religious guidance you follow.
Final Thought: Know What You Are Disposing Of
Do not start with guilt. Start with classification. Confirm whether the money is actually riba or another type of return, calculate the amount that needs to be removed, and dispose of it according to reliable religious guidance without treating it as ordinary personal spending.
And remember the Singapore specific distinction: MUIS has ruled that CPF interest is not riba because it does not arise from a loan, debt or pawn transaction. Do not throw CPF returns into the same bucket as conventional bank interest.
