Arabic (Original)
حَدَّثَنَا بَهْزٌ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ عَنْ رِفَاعَةَ بْنِ شَدَّادٍ قَالَ كُنْتُ أَقُومُ عَلَى رَأْسِ الْمُخْتَارِ فَلَمَّا تَبَيَّنَتْ لِي كِذَابَتُهُ هَمَمْتُ أَيْمُ اللَّهِ أَنْ أَسُلَّ سَيْفِي فَأَضْرِبَ عُنُقَهُ حَتَّى تَذَكَّرْتُ حَدِيثًا حَدَّثَنِيهِ عَمْرُو بْنُ الْحَمِقِ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ مَنْ آمَنَ رَجُلًا عَلَى نَفْسِهِ فَقَتَلَهُ أُعْطِيَ لِوَاءَ الْغَدْرِ يَوْمَ الْقِيَامَةِ.
English Translation
Bahz told us: Hammad ibn Salamah told us, from Abd al-Malik ibn Umayr, from Rifa'ah ibn Shaddad, who said: I used to stand at the head of al-Mukhtar, and when his lies became clear to me, I resolved -- by Allah -- to draw my sword and strike off his neck, until I remembered a hadith that Amr ibn al-Hamiq had related to me, who said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever grants a man safety for himself and then kills him will be given the banner of treachery on the Day of Resurrection."
