What is the ruling of the Shari'ah, in your view, regarding parents not being fair to their children?

The questioner : This is a listener from the Hashemite Kingdom of Jordan, Adnan Muhammad, who says in this first question: What is the ruling of the Shari'ah, in your view, regarding parents not being fair to their children?

The Shaykh : Yes. Justice among children is obligatory, based on the saying of the Prophet (peace and blessings be upon him), as established in the hadith of al-Nu'man ibn Bashir (may Allah be pleased with him and his father). His father gave him a gift, so he went to the Messenger of Allah (peace and blessings be upon him) to have him witness it. The Prophet (peace and blessings be upon him) said to him: He said, "Yes." Then he said: He said, "No." Then the Prophet (peace and blessings be upon him) said: Then he said: This hadith indicates that abandoning justice among children is injustice, and that justice is obligatory. Therefore, a person must be just among his children. However, it is preferable to favor the male over the female by giving the male the share of two females, because there is no division more just than the division of Allah (Mighty and Majestic). And Allah the Exalted said: This applies to gifts of generosity. As for a gift intended to meet a need, justice in that case is to give each of them what he needs. If it happens that a man has children, some of whom have reached the age of marriage and requested it, and his father marries them off, he is not obligated to give his other brothers the same amount of mahr (bridal gift) that he gave this son; rather, it is not permissible for him to do so, because those others did not need the mahr to be given to them. On this occasion, I would like to point out a situation or matter that some people do: they marry off their older children who have reached the age of marriage and requested it, while they have younger children. They bequeath to the younger children some money to serve as their mahr when they need to get married. They bequeath this to them after their death. This bequest is forbidden and invalid, based on the saying of the Prophet (peace and blessings be upon him): As for these children who have not married, if Allah keeps them alive until they reach the age of marriage and it is possible to marry them off, he marries them off. Otherwise, their affair is left to Allah, and they will marry with the money they obtain from inheritance or that they earn from other sources. Yes.
