My husband was engaged in trade and his business was successful. We are in Saudi Arabia, and his brother from Syria contacted him and asked for a favor; he would send machines for sale and said, 'You take half the profit, and I take the half that is not capital for him.' After the sale was completed, he sent him half the required amount and kept the remaining half, which was from the profits, but he asked him to keep it with him and include it in his work. He did so, and after a while, my husband fell ill, and the business began to collapse. Over three years, we lost everything in every sense of the word. Now he is demanding his money from us, claiming it is a debt owed to him. The money was in the business at his brother's request, and it was not a debt; it was trade. I asked my husband before his death if anyone had a debt with us, and he told me that no one had a debt with him. They put their money in willingly and at their request, and they took their capital back, leaving the profits. If God grants me, I would return it to them, but I currently have nothing from it.
