Ahmed bin Manay' أحمد بن منيع · The Book on Blood Money

that the Prophet (ﷺ) said: "The world ceases to exist is less significant to Allah than killing a Muslim man."

"Indeed the first cases to be judged between the worshippers are those of bloodshed."

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."
