Is there a financial penalty in Islamic Sharia as a punishment for verbally abusing one's father, what is its amount, and what is its basis in the Quran and Sunnah?

Allah Almighty commanded good treatment of parents and to accompany them with kindness. Dutifulness to parents is among the best deeds, and cursing parents is among the greatest major sins. You must repent sincerely and seek your father's رضا (pleasure) without giving him the mentioned amount. Deal with your siblings by preserving affection and granting respite to those in hardship among them. It is preferable to lighten their burden, while emphasizing the father's obligation to be just among his children. The mentioned financial penalty is not obligatory upon you, but if you give him something, it is a good deed.
