Abu Shuraih al-Ka'bi reported God’s Messenger as saying, “Then you, Khuza’a, have killed this man of Hudhail, but I swear by God that I will pay his blood wit. If anyone kills a man hereafter his people will have a choice, to kill him if they wish, or to accept blood wit if they wish." Tirmidhi and Shafi‘i transmitted it. It occurs in Sharh as-sunna with his isnad, but it states clearly that it does not occur in the two Sahihs on the authority of Abu Shuraih.
