Ruling on Giving a Gift to Some Children Exclusively

Question:
He says: Shaykh, this questioner married off his son and gave him an apartment as a gift. Has he wronged his daughters? He has seven daughters.

Answer:
It is not permissible to give a gift to some of your children exclusively without the others; because when Bashir ibn Sa'd came to the Messenger (peace and blessings be upon him) to witness a gift he had given to his son al-Nu'man (may Allah be pleased with them both), his wife said that the Messenger of Allah (peace and blessings be upon him) must witness it. So he went to the Messenger to have him witness his gift. He said: "Did you give every child something like this?" He said: "No." He said: "Have someone else witness this, for I do not witness injustice." He said (peace and blessings be upon him): Yes.
