What is the ruling on one who swears an oath regarding a matter, then realizes that the good lies in something else?

Question:
The questioner says: I have a son whom I asked for a sum of money, but he insulted me and hit me. I became angry with him and swore that if I performed Hajj or 'Umrah, I would invoke a curse upon him in front of the Ka'bah. I performed the prayer for guidance (istikharah) in my affair, and I do not want to invoke a curse upon him. Is there anything required of me in this?

Answer:
Do not invoke a curse upon your son; invoke guidance for him from Allah, even if he has wronged you and made a mistake. If he has wronged you and been undutiful to you, that is undutifulness, and may Allah protect us from it. Allah, Mighty and Majestic, says: . And this is the one who strikes his father and speaks ill of him; this is the greatest form of undutifulness. So the son must repent to Allah, Mighty and Majestic, and seek forgiveness from his father. And the father, too, should invoke guidance for him from Allah, forgive him, and not invoke a curse upon him. He should invoke well-being for him from Allah. He should invoke well-being for him from Allah. . So he repels this with what is best, and Allah, Mighty and Majestic, will reward him and answer his supplication for his son. He does not invoke a curse upon him; he invokes well-being for him. Yes.
