‘Amr b. Shu'aib, on his father’s authority, said his grandfather told that Suraqa b. Malik said he was present when God's Messenger allowed a father to take retaliation on his son, but did not allow a son to take retaliation on his father.
I came to God’s Messenger with my father, and on his asking who this was along with him, he replied, “He is my son; be witness to the fact.” He said, “He will not bring evil on you, nor will you bring evil on him.”*
Abu Dawud and Nasa’i transmitted it.
* This is explained as meaning that neither will be punished for the wrong done by the other.
In Sharh as-sunna there is an addition at the beginning. He said: I went in with my father to see God’s Messenger, and when my father saw what was on God's Messenger’s back he said, “Let me treat what is on your back, for I am a physician.” He replied, “You are the helper, but God is the Physician.”*
*i.e. you act in a gentle manner giving help and advice, but only God can cure.
Al-Hasan, on Samura’s authority, quoted God’s Messenger as saying, “If anyone kills his slave we will kill him, and if anyone maims his slave we will maim him.”
Tirmidhi, Abu Dawud, Ibn Majah and Darimi transmitted it, and Nasa’i added in another version, “If anyone castrates his slave we will castrate him.”
Ibn ‘Abbas reported God’s Messenger as saying, “The prescribed punishments are not to be inflicted in mosques and a father is not to be killed for a son.”
