Q: A person owes me money. After many months he decides to pay me what he owes me but, feeling guilty, he decides to pay me extra out of his own will because he feels he made me wait long for the money he owes me. Can I accept this or will this be considered to be interest?
A: Yes you may accept the extra payment because neither was it made a condition when you lent him the money nor were you expecting any extra repayment.
And Allah knows bestA: Yes you may accept the extra payment because neither was it made a condition when you lent him the money nor were you expecting any extra repayment.
