I've lent some money to a close relative of mine and I noticed he didn't pay back other family members too so what kind of punishment can I give him? Can I harm so bad that he breaks his leg or nose?
First you need to know the rule of Islam before giving to any thing to anyone
- Have two witness (min)
- Write down the transaction
- Take the signature of all the people (witnesses, lender, borrower)
If you would had all these, there would not be any problem.
Your next question: Can I harm him, break the leg or nose :) :)
It is Better to involve other relatives and make pressure on him or forgive him, because by breaking his leg or nose you are not going to get anything except something bad....
