Financial Transactions

Six years ago I gave my brother-in-law 1000 EGP to buy a gold chain, which he never did. He now wants to return 1000 EGP to me. Please note that he used this sum to conduct business and in fact gained a profit from it. Is this legally permissible?

If a person borrows gold from another and the lender agrees that the borrower returns it in gold and in its original weight, how is it to be calculated? Is it to be calculated according to its weight at the time it was borrowed or the time it is returned?

I import medical appliances. Bid requirements stipulate that the country of origin of these appliances must be only Britain, U.S.A or Germany, even though China manufactures these appliances with the same quality but at much cheaper prices. An acquaintance who works in the same field informed me that I can circumvent the laws by transshipment i.e. buying the appliances from China and bringing them to the country through one of the countries stipulated in the tender requirements. This involves claiming a false country of origin. Please note that I will sell the medical appliances I import at a much lower price than those imported from Britain, U.S.A or Germany. What is the ruling for this?

I was contracted by two individuals who represented a group of inheritors to file an inheritance case on their behalf which involved selling a building for them here in Egypt. Due to unforeseen circumstances and a severe dispute between the inheritors on one hand, and the inheritors and the buyer on the other, we were not able to reach an agreement regarding my compensation, and after I succeeded in acquiring for them a large sum I was not paid. What are my rights upon the agents and the inheritors, bearing in mind that we did not agree on my payment in the beginning?

What is the ruling on the stipulation of receiving the price for exchanging old or used gold for new gold?
Is it a condition for the seller to receive the price of the old gold from the merchant before purchasing new gold and paying for its price?
