The Ruling on Favoritism in Giving Among Children

Question:
A questioner says: I have children from two wives. One of the children is an adult in his forties and has a job, while I have young children from my second wife. Regarding the distinction between them in gifts and presents, should I give the older one the same as I give the younger one, or should I inform him of this?

Answer:
You should preserve his gift. You give your children equally, as the Messenger (peace and blessings be upon him) said: He wanted to have him witness a gift he had given to one of his children. He said, "Did you give all your children the same as this?" He said, "No." He said, "Have someone else witness this, for I do not witness injustice." In another narration, he said, "Would it please you that they be equal to you in dutifulness?" He said, "Yes." He said, "Then do not do it." Yes.
