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.”
He reported God’s Messenger as saying, “God may forgive every sin, except in the case of one who dies a polytheist, or one who purposely kills a believer.”
Abu Dawud transmitted it, and Nasa’i transmitted it on the authority of Mu'awiya.
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.
Abu ad-Darda’ reported God’s Messenger as saying, “A believer will continue to go on quickly and well* so long as he does not kill anyone unlawfully, but when he does so he will grow weary.”
Abu Dawud transmitted it.
*i.e. quick to obey God’s commands and observing well what is due to God and man.
