Round Tripping

Q: Many businesses today engage in something called “round tripping”. What they do is purchase goods, thereafter they mark the goods for export and claim the vat back, while the actual goods are not exported but are instead sold locally.

From my understanding, in the process, there are lies spoken (lying to suppliers by saying that the goods are going over the border), bribes are given (a payment is made to border officials and revenue officials to stamp documents and release payments from the revenue services) and corruption is taking place. Is this practice allowed in Islam and is it permissible for us to purchase from these businesses?

Reselling an item at a higher price

Q: My husband is working in a private Afghan company that stores oil for America. Sometimes the Americans ask my husband for some goods like paint, furniture or other things. My husband asks the price from the shopkeeper and buys the goods then gives the goods with an increased price to the Americans.

For example, the furniture price is 300 dollars and my husband gives the price as 500 dollars, even the Americans know the real price but they accept the price that my husband gives.

I told my husband that this money is haram but he says that I am not their employee, I work for another company. They ask me to buy goods for them and I give them a quotation then they buy it. This is business. I don't directly tell them that I increased the price but they know. They accept it because they trust me and they need one person to do their work for them since they can't directly buy those things. I spend my time and effort for them in getting those things so the money is not haram. Kindly tell me whether the money my husband charges them is haram or halal. 

Selling animals to an abattoir that pays according to the weight of the animal after slaughter

Q: Is it permissible for a Muslim farmer to sell his animals to an abattoir that will pay him only after they slaughter and skin etc.? Nowadays, most abattoirs first slaughter the animal. They then grade the meat and accordingly pay the price on the hook. The price per kg is fixed e.g. A grade R40/kg, B grade R30/kg, C grade R20/kg. Is this sale permissible due to the price of the animal being unknown at the time of the sale? Will the ruling change if both parties are willing and agree, and generally this doesn’t lead to any problems as this has become the norm in dealing with abattoirs? If not, is there a way to make the sale valid such as the farmer making the abattoir his representative or leaving the animals by the abattoir and making them responsible without concluding the sale? How would it work out in the situation where the abattoir is non-Muslim owned?

Deceiving people in business

Q: My aunt gave me a business idea that firstly I should sell food with good fillings like I should sell pizza with some good amount of filling and as soon as people would start buying it more, then at that time I should use less fillings for the pizza. Is this considered fraud, even though I didn't appreciate her or said that her idea is right. So is my aunt doing fraud - sin?
