Marthad bin Abdullah al-Yazani reports the statement of a Companion: The Prophet (peace and blessings be upon him) was asked about the one who kills and the one who orders the killing, and he said: "The Fire will be divided into seventy parts: the one who gave the order will receive sixty-nine parts and the killer will receive one part, and that will be sufficient for him."
Ahmad recorded this narration, and its narrators are the narrators of the Sahih, except for Muhammad bin Ishaq, who is thiqah (trustworthy) but is a mudallis.
