Sahih al-Bukhari · Book 92: Afflictions and the End of the World · “Do not renegade as disbelievers after me by striking the neck of one another.”
Narrated Jarir:
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ ، حَدَّثَنَا شُعْبَةُ ، عَنْ عَلِيِّ بْنِ مُدْرِكٍ ، سَمِعْتُ أَبَا زُرْعَةَ بْنَ عَمْرِو بْنِ جَرِيرٍ ، عَنْ جَدِّهِ، جَرِيرٍ قَالَ قَالَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم فِي حَجَّةِ الْوَدَاعِ " اسْتَنْصِتِ النَّاسَ ". ثُمَّ قَالَ " لاَ تَرْجِعُوا بَعْدِي كُفَّارًا، يَضْرِبُ بَعْضُكُمْ رِقَابَ بَعْضٍ " .
The Prophet (ﷺ) said to me during Hajjat-al-Wada`, "Let the people keep quiet and listen." Then he said (addressing the people), "Beware! Do not renegade as disbelievers after me by striking (cutting) the necks of one another."
