Sa'id ibn al-Musayyib سعيد بن المسيب بن حزن أبو محمد القرشي · The Book on Blood Money

that the Messenger of Allah (ﷺ) said: "The father does not suffer retaliation for the son."

"A man bit the hand of another man. The man who was bitten pulled his hand out, causing two of his incisors (teeth) to fall out. They brought their case of the Prophet (ﷺ). So he said: "One of you bites his brother like the stallion bites? There is no blood-money for you.' So Allah Most High revealed: Wounds, equal for equal."
