Assalamualaikum Mufti Saab, 
Hope you are doing well.

I came across this platform that provides loans on an income percentage share basis. Below are a few details from their website (fundmebff.com). Can you please advice if getting a loan from here is permissible?

Jazak Allah khair.

Product and its Benefits
Our Product: It is not a loan. We provide you with the money you need up front and in return, when you are working, you share a fixed percentage of your income for an agreed upon fixed period.

A major advantage of our product: Your payments are designed to stay affordable. If your income decreases, your payments decrease too!

How do we make money?

For each investment we make, we have a target rate of return. Unlike a loan, we do not hold you liable if we don’t reach our target rate of return. That’s why our Income-share agreements are truly investments and not loans. We only do well if you do well.

Historically, our target rates of return have been at least %25 less than what an interest-bearing loan for the same amount and over the same period would cost.

What is the funding process?

1- Start with filling out the application for funding.

2- If we’re interested in your initial application we may ask for some supplemental information.

3- After providing the supplemental information, we will work with you to reach an income-sharing arrangement that makes sense for both of us.

4- After agreeing to the terms, we will transfer the funds to your designated account.

5- When your income share period starts, you start sharing your income with us at the agreed-upon fixed portion and for the agreed-upon fixed period of time.
