Q: Zakat is wajib on four things and out of the four, one is تجارت. So if someone decided to sell some of their belongings on eBay or Amazon, etc., will they have to pay zakat on it?

Q: I've bought an item on eBay and after receiving the item, I requested a refund for the money because it was not as stated. The money was returned and according to eBay policy, the seller is to pay the shipping fee for the return. I've been trying to get in touch with the seller for almost two months now but they have not responded. I would like to know what I am to do with the item I had previously bought?
