Narrated Abdullah ibn Umar:
AbdurRahman ibn Samurah said: I was holding the hand of Ibn Umar on one of the ways of Medina. He suddenly came to a hanging head. He said: Unhappy is the one who killed him. When he proceeded, he said: I do not consider him but unfortunate. I heard the Messenger of Allah (ﷺ) say: If anyone goes to a man of my community in order to kill him, he should say in this way, the one who kills will go to Hell and the one who is killed will go to Paradise.
Abu Dawud said: Al-Thawri has transmitted it from 'Awn from 'Abd al-Rahman b. Sumair or Sumairah ; and Laith b. Abu Sulaim transmitted it from 'Awn from 'Abd al-Rahman b. Sumairah.
Abu Dawud said: Al-Hasan b. 'Ali said to me: Abu al-Walid transmitted this tradition to us from Abu 'Awanah, and said: It (the name Ibn Samurah) is in my notebook Ibn Sabrah. The people also transmitted it as Samurah and Sumairah. These are wordings of Abu al-Walid.
