حَدَّثَنَا عَمْرُو بْنُ رَافِعٍ، حَدَّثَنَا مَرْوَانُ بْنُ مُعَاوِيَةَ، حَدَّثَنَا يَزِيدُ بْنُ زِيَادٍ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ أَعَانَ عَلَى قَتْلِ مُؤْمِنٍ بِشَطْرِ كَلِمَةٍ لَقِيَ اللَّهَ عَزَّ وَجَلَّ مَكْتُوبٌ بَيْنَ عَيْنَيْهِ آيِسٌ مِنْ رَحْمَةِ اللَّهِ " .

Amr ibn Rafi reported to us: Marwan ibn Muawiyah reported to us: Yazid ibn Ziyad reported to us, from al-Zuhri, from Said ibn al-Musayyab, from Abu Hurairah, who said: The Messenger of Allah (Allah bless him and grant him peace) said, ‘Whoever assists in killing a believer by even half a word will meet Allah, Mighty and Majestic, with “Despairing of Allah’s mercy” written between his eyes.’
Notes and open questions — unreviewed
The Arabic says ‘half a word,’ not ‘half a world’ as in the English witness.
