Q: My mother lent me R 15 000 which I was able to pay back. I invested the R15 000 on her behalf. I invested more as a gift but now had to use some of that money but the loan amount is still safe. Can I use the extra money without having to pay it back as we never agree to more that just the R 15000?
And Allah Ta’ala (الله تعالى) knows best.
