Using earned interest to pay obligated interest
As-salamo alaikom, when I got married about 2 years ago, my wife had about 2000 pounds to pay as a student loan. so, i paid this loan off for my wife as i had some savings. I used the interests that i had on my savings to pay the interests of her loan then i paid the actual loan with my own money. was that right? can i pay interest with interest. keeping in mind that i do not accept interest and i would have normally gave it away.
