Using money which was transferred into one's account by an unknown person
Q: I have a savings account in a bank. Someone transferred extra money which does not belong to me into my account. I enquired alot from the bank but they told me that it was from some government court. I called the bank more than 5 times and told them that I have no encounter with the court. They cannot do anything or provide any information. I waited for a long time for the owner to claim their money or contact me but unfortunately nobody claimed it. I'm in need of money for my marriage but my heart does not allow me to touch that amount. Please tell me if the amount is haraam or halaal if I spend it?
