Q: I have seven sons and five daughters and I work in trade. My elder two sons have worked with me for ten years. After I spent money on them and paid their marriage expenses and they had children, they demanded a certain percentage of the next profit or to assign a fixed salary for them. They asked me to do so for I asked one of them who is a teacher and earns 7,000 Riyals per month to resign from his work so he could work with me in trade. I handed all my money over to them to dispose of as they want and did not prevent them from anything they wanted.However, I did not single them out for anything. It is worth mentioning that the youngest of my children is one year old. I have two wives and perhaps I will have other children. I fear that I might treat any of my children who work with me in business unjustly because they have children as I have. At the same time, I do not like to treat my young children unjustly if I give something to those who work with me. Could you kindly advise me in this regard.
