How to use the Musaffa’s purification calculator in the app
Last updated 9 months ago
Purification is an important part of halal investing. Even when you invest in Shariah-compliant stocks, sometimes a small amount of income may still come from non-halal sources like interest. That portion doesn’t belong to you — it must be purified by giving it away.
With the Musaffa app, purification is simple. This guide will show you how to do it step by step.
Step 1: Why purification matters
Before we start, let’s understand why purification is necessary:
Some halal companies may still earn a small amount from non-permissible sources (like bank interest or non-halal businesses).
As an investor, you may indirectly earn a portion of this income.
Islam teaches us to remove that part to keep our income clean and halal.
Purification helps ensure that your profits are ethically earned and religiously compliant.
Step 2: Access the Purification Calculator
Musaffa simplifies purification with its Purification Calculator.
Here's how to access it:
Open the Musaffa app
Go to the Explore page
Tap on "Purification Calculator"
The calculator helps you determine the exact amount you need to purify.

Step 3: Enter your stock details
Once you open the calculator, you’ll need to enter a few basic details:
The stock name or ticker symbol
The number of shares you owned
The date you bought the stock
The date you sold the stock (if you already sold it)
After you enter this information, tap "Calculate" — the app will show you how much money you need to purify based on your ownership.

Step 4: Donate the purification amount
Now that you know the amount to purify:
Choose a trusted charity or cause
Donate the calculated amount
This step completes the purification process. You are now removing the impure income and keeping only what is halal.
Step 5: Make purification a regular habit
Purification is not a one-time task — it’s something you should do whenever you earn from your investments.
You should calculate and purify whenever you sell a stock for a profit. By repeating this regularly, you ensure that your entire investment portfolio remains pure and compliant with Islamic values.

Purification is a must for every Muslim investor who wants to stay true to Islamic principles. It’s not hard — and with Musaffa, it’s even easier.
