Settling one's debts
Q: My father had been for Hajj over 10 years ago. At the time he had a very close friend who he had owed some money to. Before going for hajj, he went to his friend to pay off whatever money he owed him but his friend refused, saying go and enjoy your hajj, and being friends, he kept saying don't worry bout all of that now. So my dad went for his hajj, when he got back, a short time later, his friend past away in a car accident. My father is now older and is not working anymore due to his health , but because his friend never directly say don't pay me, its been worrying my father and so he decided to save up the money that he would have had to pay his friend and give it to his friend's son, who has no knowledge of this. After many months of saving, as he is now unemployed, he managed to save the money and was going to get the money sent to the son via a mutual friend within the week. Then within the weekend his house was burgled and the safe was stolen with the money in it. Does my father still have to save again and pay the money?
