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.

حَدَّثَنَا أَبُو الْوَلِيدِ الطَّيَالِسِيُّ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ رَقَبَةَ بْنِ مَصْقَلَةَ، عَنْ عَوْنِ بْنِ أَبِي جُحَيْفَةَ، عَنْ عَبْدِ الرَّحْمَنِ، - يَعْنِي ابْنَ سَمُرَةَ - قَالَ كُنْتُ آخِذًا بِيَدِ ابْنِ عُمَرَ فِي طَرِيقٍ مِنْ طُرُقِ الْمَدِينَةِ إِذْ أَتَى عَلَى رَأْسٍ مَنْصُوبٍ فَقَالَ شَقِيَ قَاتِلُ هَذَا . فَلَمَّا مَضَى قَالَ وَمَا أَرَى هَذَا إِلاَّ قَدْ شَقِيَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ " مَنْ مَشَى إِلَى رَجُلٍ مِنْ أُمَّتِي لِيَقْتُلَهُ فَلْيَقُلْ هَكَذَا فَالْقَاتِلُ فِي النَّارِ وَالْمَقْتُولُ فِي الْجَنَّةِ " . قَالَ أَبُو دَاوُدَ رَوَاهُ الثَّوْرِيُّ عَنْ عَبْدِ الرَّحْمَنِ بْنِ سُمَيْرٍ أَوْ سُمَيْرَةَ وَرَوَاهُ لَيْثُ بْنُ أَبِي سُلَيْمٍ عَنْ عَوْنٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ سُمَيْرَةَ . قَالَ أَبُو دَاوُدَ قَالَ لِي الْحَسَنُ بْنُ عَلِيٍّ حَدَّثَنَا أَبُو الْوَلِيدِ - يَعْنِي بِهَذَا الْحَدِيثِ - عَنْ أَبِي عَوَانَةَ وَقَالَ هُوَ فِي كِتَابِي ابْنُ سَبْرَةَ وَقَالُوا سَمُرَةَ وَقَالُوا سُمَيْرَةَ هَذَا كَلاَمُ أَبِي الْوَلِيدِ .
