Giving a gift or present to one of the sons specifically

Question:
As for a Muslim during his lifetime, he is bound to have a preference for one of his sons, especially those who cooperate with him. He might say: I have a son who is always with me and cooperates with me, and I want to give him money specifically. What is the ruling on that?

Answer:
Answer: It is not permissible to give him specifically except in the case of wages. If you want him to work for you for a specific wage and salary, there is no harm in that in exchange for this work. This is not giving him a specific gift; rather, he is a wage-earner like any other wage-earner.
