Al-Imām al-Bukhārī relates: Ḥajjāj narrated to us. He said: Shuʿbah narrated to us. He said: ‘Alī ibn Mudrik informed me, from Abū Zur’ah,
from Jarīr (may Allāh Almighty be content with him), that: The Prophet ﷺ said during the Farewell Pilgrimage: “Silence the people.” Then he said: “Do not return to disbelief after me, striking the necks of one another.”
حَدَّثَنَا حَجَّاجٌ قَالَ: حَدَّثَنَا شُعْبَةُ قَالَ: أَخْبَرَنِي عَلِيُّ بْنُ مُدْرِكٍ، عَنْ أَبِي زُرْعَةَ، عَنْ جَرِيرٍ
أَنَّ النَّبِيَّ ﷺ قَالَ لَهُ فِي حَجَّةِ الْوَدَاعِ: اسْتَنْصِتِ النَّاسَ. فَقَالَ: لَا تَرْجِعُوا بَعْدِي كُفَّارًا، يَضْرِبُ بَعْضُكُمْ رِقَابَ بَعْضٍ.
