Is it an exception to being just among one's children to give to the son who serves him, to the exclusion of his other brothers?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Is it an exception to being just among one's children if the son is with his father, serving him in his house, and the other sons are not with him, so he gives to the one who serves him, who also serves his sisters, and withholds from the rest?

Answer:
No, this is not an exception. This falls under the prohibition; it falls under the prohibition. The only exception is if the son is in need, or has debts, or is ill and unable to earn a living; then he gives to him, to the exclusion of his brothers, out of consideration for his need. But if he is with him, that is dutifulness; that is dutifulness toward his parents, and it is obligatory upon him. This is obligatory upon him. However, if the son wants to leave and not stay with him, while the father wants him to serve him and help him with his business, he can pay him a salary, just as he pays others, and consider him a hired worker. There is nothing wrong with considering him a hired worker in exchange for his work. Yes.
