وَحَدَّثَنِي أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو بَكْرِ بْنُ خَلاَّدٍ الْبَاهِلِيُّ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ وَاقِدِ بْنِ مُحَمَّدِ بْنِ زَيْدٍ، أَنَّهُ سَمِعَ أَبَاهُ، يُحَدِّثُ عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ فِي حَجَّةِ الْوَدَاعِ " وَيْحَكُمْ - أَوْ قَالَ وَيْلَكُمْ - لاَ تَرْجِعُوا بَعْدِي كُفَّارًا يَضْرِبُ بَعْضُكُمْ رِقَابَ بَعْضٍ " .
Abu Bakr ibn Abi Shaybah and Abu Bakr ibn Khallad al-Bahili narrated to me; they said: Muhammad ibn Ja'far narrated to us; Shu'bah narrated to us, from Waqid ibn Muhammad ibn Zayd, who heard his father relate from Abdullah ibn Umar, from the Prophet (peace and blessings be upon him), who said during the Farewell Pilgrimage: ‘Woe to you—or he said, “May you be ruined”—do not return to disbelief after me, striking one another's necks.’
