What is the ruling on giving a gift to some of one's children exclusively?

Question : The questioner says: Honorable Shaykh, may Allah keep you safe. My mother owns a house, and this house collapsed, so I built it and laid its foundation at my own expense. She said to me, "O my son, your brothers are of corrupt character, so I will write this house to you as a sale and purchase, excluding your brothers." Is that permissible? We raised this based on the Shaykh's approval.

Answer : It is not permissible for a mother to give a gift exclusively to some of her children. This is based on the saying of the Prophet (peace and blessings be upon him) The fact that some of the children are wicked, sinful, foolish, or undutiful to their parents does not justify the mother giving a gift exclusively to some of her children, and the same applies to the father. Yes, if the father or mother wants to encourage his or her children, saying, "Whoever memorizes the Qur'an by heart will receive such and such," there is nothing wrong with that. "Whoever seeks knowledge will receive such and such," there is nothing wrong with that, because this is not an exclusive gift to a specific person, but rather for his work. Giving exclusively for a deed that all the children can perform is not a problem, may Allah keep you safe. But you will give him the house. Even if it is on the cost of the land. Yes.
His sons, and he said, "Whoever memorizes the Qur'an by heart will receive so much and so much." This is permissible. "Whoever seeks knowledge will receive so much and so much." This is permissible, because this is not a specific designation for a particular person, but rather for his work. There is no harm in designating a work that all the sons can perform. May Allah keep you safe. But you will give him the house, even if it is on land that you are maintaining. Yes.
