The Ruling on a Father Selling to One of His Sons

Question:
I want to speak to the Shaykh, may Allah prolong your life. You and him, if Allah wills. Please go ahead. I have children and I have wealth, and some of my children are married while others are not. Some are sons and some are daughters. Each of them is independent. As for my personal situation, I was unable to handle it, so I put it up for sale and called one of the children with the consent of his brothers. So he did not give me money, meaning deferred money. And he is still not married. The one who is working is still not married. So I intended to make it in exchange for my marriage. Do you know if the seller is correct in this, or is there something wrong with it? Yes, O Shaykh. The first question. Wait, he says his children, Honorable Shaykh, and his wealth, and he gave one of the children his share over the rest of his brothers, selling it to him, a sale, O Honorable Shaykh. Is this sale, he asks, valid?

Answer:
If he favored him in the sale, then it is not permissible, but if he sold to him as he sells to people and did not favor him, then there is no harm in that. Yes.
