Gold, Silver and Money

Q: I went to a jeweller with some items of old gold jewellery to to get new jewellery. He gave me 2 options:

1. He melts the old jewellery and makes new ones and I pay him for his labour.

2. If there is some piece of jewellery which I like, we can swop the both.

I told him give me some time to decide. In the meantime, he sent me a picture of an item which was also gold which I liked, so I told him to please keep it for me and I will come to his office and we'll make the deal.

When I finally go there, he informs me that in order to keep that item for me, he had to swop my jewellery for it. This was done without first asking me and without my permission. So now my jewellery is gone and he tells me I must take the new item. I asked him regarding the difference in weights of the two as both were gold. His reply was "the difference was very small, don't worry about it".

My problem is that I understand that him doing that straight swop was not permissible according to shariah as gold for gold must be exact and even a "small difference" is not permissible. But now my jewellery is gone and cannot be retrieved, and I'm left with no option but to take this new item. What do I do in this situation? Will I be sinful for taking this item knowing that he got it through a riba transaction? And if I don't take it, I will lose out as he wouldn't pay me for my gold.

Also, with regard to the difference in the weights, I don't even know which was more or less as he wouldn't tell me clearly (although it seems to me that mine was the more).

Q: My father has exchanged money, but it was not simultaneous. So, the transaction was haraam. But what about the money? My father has exchanged 10,000 SEK to different currency. So will the whole 10,000 SEK of my father be haraam? If so, how can we make it halaal?

If I tell my father to return the money to the other party, he is not going to listen me.

Q: FNB offer a service where one can invest in Kruger Rand gold coins through them. They then store it for you at a fee of 0.86%pa.

-If one wants to sell the coin back to them, its done at the click of a button.
-If one wants the physical coin, they can arrange for it to be delivered to you at a cost.
-Prior to requesting the coin, I'm not sure if they keep the physical coin or not.

Please advise if it will be permissible to purchase a coin through them in this manner.

Q: I have R1000 worth of R100 notes. However, these are the old notes and I want to change them for the new R100 notes. The agent said that he will change the old notes for the new notes, but he will charge me R10. Is this permissible?

Q: If one wishes to buy gold coins or gold jewellery, then what are the conditions for the transaction to be valid? Are there any particular masaa’il related to this?

Q:

1. If someone trading in jewellary, takes gold from someone as an investment into his business, does he have to return it in the form of gold or he has the option to return it as either gold or cash?

2. What if the initial deal was to return in the form of gold?

3. The price of gold has tremendously increased and he will return a huge amount (the gold he took as an investment does not exist anymore), so he either will pay the investors cash or gold, is this extra amount interest?

4. The investors gave him gold with a condition of getting a monthly profit, but in fact they were getting a monthly fixed amount regardless of the profit or loss. Is this fixed monthly payment interest?

5. Is it fine to take the orders to make jewellery and take some cash initially and at the time of delivery receive the rest or the whole deal should take place in one session?

6. What if the customer does not pay at the time he receives the jewellery and pays later, is it permissible?

Q: Someone wants to buy gold but does not have enough funds and decides to give some amount to the seller and book the gold at the price of the day of booking to prevent paying more by the time he gets more funds. In this case, the gold price may go up or down on the day he will actually give the remainig amount and takes the gold. 

Is this a permissible situation or one needs to do the whole deal of paying money and taking gold in the same sitting?

Q: My question is about online options trading. In this we trade between currencies. It is like tearing currency for 1, 5 or 15 minutes. So if the value of the currency goes up in that time frame (which we can predict by doing some calculations and indicators) and if the currency goes down we lose money. It is between two currencies like we trade Euro for USD. We buy USD by paying in Euros and when it is expected to go up in value or USD/EURO. The money transaction is instant and simultaneous. So, if we make a prediction the money is deducted from our account instantly and if we predict rightly we get profit. Mostly we get profit. Can you please guide me is it Halal or Haram?

Q: I own a jewellery store. We offer our customers a 'trade-in' service where they bring their old jewellery to us, we evaluate it and determine its worth, and then the customer takes jewellery of their choice to the value of the jewellery that was traded-in.

Is it correct to deal in this manner? If not, how should we conduct the deal?

Q: Is it permissible to sell gold and silver plated jewellery?
