I never saw the Messenger of Allah (ﷺ) that some dispute which involved retaliation was brought to him but he commanded regarding it for remission.
Sunan Abi Dawud Book 41, Hadith 4
← Previous Hadith The Prophet (ﷺ) said: If a relative of anyone is killed, or if he suffers khabl, which means a wound, he may choose one of the three things: he may retaliate, or forgive, or receive compensation. But if he wishes a fourth (i.e. something more), hold his hands. After this whoever exceeds the limits shall be in grave penalty.

Sunan Abi Dawud Book 41, Hadith 3 Next Hadith → A man was killed in the lifetime of the Prophet (ﷺ). The matter was brought to the Prophet (ﷺ). He entrusted him to the legal guardian of the slain. The slayer said: Messenger of Allah, I swear by Allah, I did not intend to kill him. The Messenger of Allah (ﷺ) said to the legal guardian: Now if he is true and you kill him, you will enter Hell-fire. So he let him go. His hands were tied with a strap. He came out pulling his strap. Hence he was called Dhu an-Nis'ah (possessor of strap).
